I've produced a series of videos (and a playlist) on Youtube for getting the "No Refunds" Achievement ("Finish the game in under 4 hours. See you at GDQ!"). For this guide, I've created a section for each video, stuck a link to that video at the top, and then included the outline with timestamps that I included in the video. So, hopefully, if you don't want to watch videos, those outline steps will help you do the task.

There are two other Achievements that can probably be done using the same process:

• "Old Game Master" ("Assert your independence and beat Old Game Minus entirely in singleplayer"), and
  
• "Old Game Alliance" ("Tolerate another person long enough to beat Old Game Minus entirely in coop").

Those have to be run in Old Game Minus (OGM) mode (obviously). But, the only difference between that and a regular run is that OGM HAS to be done in under 4 hours and only gives you 3 lives. The videos I recorded do show where an additional 3 lives can be found in OGM mode (via bobbleheads).

I say "probably" up above, because I haven't actually done my OGM run yet. But, I don't see any problems.

And, if you'd rather just see the whole playlist on Youtube instead of seeing it in sections here, here's a link to that:

At this point, I believe the only needed upgrade for a full runthrough is the Shock Fruit Stabilizer (which I won't get for a while). So, I'm upgrading everything that looks reasonable on the assumption I'll be getting more resources by then: Advanced Battery (100 silicon), Fast Reload (100 aluminum, 1 Alien Alloy), Better Utility Belt (200 aluminum, 200 silicon, 1 Alien Alloy) (starts at 0:05)

      1. GOO: bomb crack in back wall. (starts at 18:38)
         
      2. GOO: out of cave to left near PBs in grass. (starts at 19:21)

      4. ALIEN ALLOY: all the way down right path and drop down to the bottom again. Since there are no bombs handy, can't break crack for goo. So, drop down and teleport back to Cliffs of Mt. Gzarfyn. (starts at 20:06)
         
      5. Teleport back to the ship to deposit your resources and make sure your weapons are updated. The next step is the Cragclaw Boss battle (starts at 21:41)

   3. FUEL #3: Toss bomb up to crack in cavern mouth above jump pedestal thing, jump up and get fuel #3 (starts at 11:34—I don't get a successful jump until 13:00—looks like you have to be just barely on the corner)
      
   4. GOO: jump up in arch to right of jump pedestal thing (in the video, I do this before jumping up for the fuel—starts at 11:57).

   1. Shoot yellow eye, shoot yellow holes; repeat with acid on amber coated holes (dull brown/yellow); repeat again with all amber coated holes (I've sped the fight up in the video since I'm so bad at it and it takes so long - it starts at 18:58 and ends at 24:28 if you want to skip it).
      
   2. Down to Caustic Alter for Blight Bomb Stabilizer
5. SHIP: Blight Bomb Stabilizer (200 carbon, 150 silicon—starts at 25:15)

1. Teleport to The Enigmatic Spire (starts at 0:05)
   
   1. Across to spire, scan statues and door (that'll unlock Static Panic quest for Shock Fruit Stabilizer—starts at 0:12)
      
   2. EXTRA LIFE 3 (only in Old Game Minus): go right all the way to jump pedestal area. Final bobble is on top of rock before that pedestal. I shoot the rock where the bobble will be in Old Game Minus (starts at 0:34)

2. Xerophilous Landing:
   
   1. Head back to tether by big arches, across to island, off to the right across tether to the island where the broken portal is. But ignore it—starts at 1:57).
3. Broken Portal Island: instead of going to the portal, go left to picnic tables and grapple up to the Pillars of Xzorgana area, grapple up some more, across to island, grapple up even more to the portal, activate it and teleport back to the ship to deposit your resources. Turn around and head right back to Pillars of Xzorgana. (starts at 2:56)

   1. FUEL #4 is on top of tall pillar by jump pedestal thing (starts at 5:15)
      
   2. FUEL #5 and ALIEN ALLOY: Drop down, go to west bridge and drop down to cavern underneath. Grapple to final fuel and Alien Alloy. It doesn't matter if you die here since all you care about is that final unit of fuel (and it saves the trouble of getting back to the ship—starts at 6:42)
5. SHIP: I'm ending this before launching for the "bad ending" since I want to continue this video series to the "good ending." I'm not sure what would happen to the good ending if I came back to finish after getting the bad ending. See the next video for the actual launch and "No Refunds" Achievement.

Bad Ending: For those not in Old Game Minus, you can get the bad ending to get the "No Refunds" Achievement. That's what this video shows. If you ARE in Old Game Minus mode, then you'll have to go all the way to the good ending and kill Teratomo. The remainder of this video series will show that.

1. Pillars of Xzorgana: Since I died gathering my last fuel, the game kindly put my loot by the portal (which I picked up). If you didn't die there, you won't have this. Anyway, just tether across from south side of island and unlock the "Crackling Pedestal" portal. Note that there's an Alien Alloy beyond the portal that you can get by killing the whaac-a-mole critters around it. Since I have more Alien Alloy than I can use, I'm not bothering (starts at 0:06)
   
2. Crackling Pedestal:
   
   1. Jump across to the south to the actual "The Crackling Pedestal" island (starts at 0:56)
      
   2. At the far end of the island, scan the "Shock Fruit Stabilizer Shrine" (starts at 1:04)
      
   3. Protect the shrine from the waves of PBs by using shock fruit from the two trees on either side of the shrine. "Toss" the fruit at the PBs to shock and immobilize them (so their tails are up) and shoot the yellow balls at the end of their tails. "Shrine Stability" will show in the upper-right of your HUD so you'll know how you're doing (starts at 2:14)
      
   4. When the PB waves stop, extract a sample from the shrine and head back to the ship (starts at 4:30)
3. SHIP: Shock Fruit Stabilizer upgrade (100 aluminum, 200 carbon) (starts at 5:14)

1. I didn't do this earlier since, with the bad ending, the upgrades weren't necessary. Going for the good ending, those upgrades will make life easier. In retrospect, I should have kept the tasks in mind throughout the game and done them as I went along. Skip if time is tight. This will unlock:
   
   1. Bounce Shot,
      
   2. Advanced Battery 2 (200 silicon, 1 alien alloy),
      
   3. Improved Damage 2 (100 carbon, 1 alien alloy),
      
   4. Bombegranate Booster (100 silicon, 1 alien alloy),
      
   5. Precious Stuff Magnet (250 carbon, 1 alien alloy),
      
   6. Triple Thrusters (200 carbon, 1 alien alloy),
      
   7. Orange Goo Detector (100 aluminum, 100 silicon, 1 alien alloy),
      
   8. Alien Alloy Detector (250 aluminum, 250 silicon, 2 alien alloys).
2. Live Samples (Approach the following live creatures and tag them using the Live Sampler):
   
   1. Pufferbird: cave right outside Landing Site portal (at 0:30)
      
   2. Babouushka: two-headed chicken in Towering Crystals area (at 3:34)
      
   3. Pikemander: big, spinning lizards. One up path from Meteor Crater portal (starts at 5:24)
3. Nuke It (Kill four creatures with an Alpha Pufferbird explosion): group in left side of ice fields by big skeleton. Bait them all, then shoot alpha (at 2:09)
   
4. Safety First (Fall 50 meters and save yourself with the Thrusters): Pillars of Xzorgana, and jumping off of the southwestern edge, but any big drop will do. Make sure you hit your thrusters just at the last second. Unfortunately, I couldn't remember a better way to get to a portal, so there's a lot of running through the wilderness (starts at 7:28)
   
5. Flight Risk (Kill 5 ground creatures while they are airborne): kick PBs and shoot them while in air
   
   1. 1:30
      
   2. 1:34
      
   3. 4:00
      
   4. 6:32
      
   5. 6:49
6. Scanning (Use your scanner to document at least 25% of the planet’s ecosystem): should have this by now.
   
7. SHIP: Print various upgrades (starts at 9:21)

1. Pillars of Xzorgana (start at 0:05)
   
   1. Scan stomp circle behind pillar to unlock mission (start at 0:15)
      
   2. Grapple to island above and to east (start at 0:36)

   2. All the way to top and activate Tears of T'bo portal (start at 1:02)
      
   3. To east, enter orange covered "arena" area (Depths of Fnndddkkertt), scan and beat Slamphibian (start at 2:09)
      
   4. Afterward, ground will break and you'll have to fight some more. That will open the door to the Stomp Booster Shrine (start at 4:38)
      
   5. Get sample, activate Slamphibian Pit portal to your right and go back to ship to print it. I was short of carbon, so I had to go out and farm it from the PBs (start at 5:37)
3. SHIP: Stomp Booster upgrade (200 carbon, 100 silicon) (start at 6:31)

1. Start from the Enigmatic Spire (starts at 0:04)
   
2. From the jump pedestal near the rear, grapple around between the islands to the left to reach the spire (starts at 0:46)

4. Activate the palm button (starts at 2:29)
   
5. GOO: Jump up to upper level for goo at west end (if you don't pick this one up now, later, if you want it, you'll have to either climb the outside of the tower or drop down from the Tears of T'bo—starts at 3:01)
   
6. Head back to ship (optional—I did this just for a convenient save for the video—starts at 4:11)

1. Enigmatic Spire: enter central spire and activate it (I don't know if scanning all those tablets on the bottom floor is necessary, but I did it just to be sure). Head back to the portal (starts at 0:05)
   
2. The Broken Bridge: teleport in, grapple across, through door, activate the portal. I checked my supplies and found I needed some items, so I transported out to get some and came back. Head forward and activate the elevator down (starts at 1:18)
   
3. Heading down the Spire: the elevator will make three stops on the way down. At each stop, you'll have to shoot three glowing, yellow orbs to get the elevator to continue to the next level (start at 4:13)
   
   1. Stop 1: this level's not too bad, just miscellaneous foes:
      
      1. Root Orb 1: southeast side of the bottom level, behind root (the yellow glow should help spot it—starts at 4:25)
         
      2. Root Orb 2: head to north wall and grapple one level up, on the north wall. Activates electric bugs, so it might be worth doing the third orb before this one. But, you can mostly ignore the bugs since they stay on that level
         
      3. Root Orb 3: On the south wall, up several levels, behind an electric door. I just leaned in and shot it instead of entering since the door activates and requires an electric shock to get out (starts at 5:07)
         
      4. Activate elevator to next level down (starts at 5:49)
   2. Stop 2: this level adds dripping lava, so watch out for that (starts at 6:11)
      
      1. Root Orb 1: face the northeast wall, one level up, you can see a root entering a glass pod. The orb is two pods to the left. There's a health plant one clump of pods to the right(starts at 6:43)
         
      2. Root Orb 2: on the west wall, there's a cave behind a block (you can see it, along with the blue grapple points, at 6:59 in the upper-left). Grapple in, quickly bomb the crack and jump up to kill the orb. Otherwise you'll have to fight the monsters that come out of the floor.
         
      3. Root Orb 3: on the south wall of the bottom level, behind some pods. You should be able to see the yellow glow to help locate it (starts at 8:21)
         
      4. Activate the elevator to next level down (starts at 9:30)
   3. Stop 3: this level adds in some pus shooters (do NOT shoot the big, obvious orb on the southeast wall as that activates them—starts at 9:49)
      
      1. Root Orb 1: on the southeast wall of the bottom level, behind some pipes (yellow glow should help find it), through stomp block (starts at 10:07)
         
      2. Root Orb 2: on the west wall up in cave. To avoid my thrashing looking for them, from the main level facing the "bad" orb on the southeast wall, the cave is about 1/3 of the way around clockwise. It's bracketed by health plants in pods (the one on the left is below the cave and the one on the right is on the same level as the cave—there's also a bombegranate plant there). Fight Slamphibian and enter his back cave for orb.
         
         EDIT: I just completed another run through the game. It turns out you can bypass the fight with the Slamphibian. When he breaks through the wall and jumps down to fight, just run past him, jump up into his entry hole, shoot the orb and run out. (starts at 10:46)
         
         
      3. Root Orb 3: On the southeast wall on the main level. Shooting it kicks off the pus shooters (starts at 20:10)
         
      4. Active elevator to descend to final boss fight (starts at 21:14)
   4. Stop 4 (Teratomo): when he shoots fire on all the back ledges, jump to the middle ledge and continue shooting him there (I didn't do that and died).
      
      1. Phase 1:Shoot yellow orbs on jaw and tentacles. When enough gone, will roll out tongue. Walk up and grab the seed pod (first try starts at 21:26, second at 24:40)
         
      2. Phase 2: ditto (first try starts at 23:26, second at 26:28)
         
      3. Phase 3: ditto (starts at 28:37)
         
      4. After you "leave" the area, head back to the ship. Note that I officially died in this fight (that makes three, but I had the three extra-life bobbles, so I'd still be good in Old Game Minus mode) (starts at 30:47)
   5. Back to ship: I quit the game here so I could re-enter and include the run duration in the video: 3 hours and 42 minutes. A bit closer to the four hour limit than I'd like, but still good. The "No Refunds" Achievement didn't pop here since I'm in a regular mode game and got the Achievement with the bad ending a way back. I believe it should pop when the credits start to run after the good ending movie (starts at 31:41)

In regular game mode, getting to the bad ending took only 2 hours and 24 minutes. So, there's no problem with getting the "No Refunds" Achievement that way.

If you're trying it in OGM, the whole video series (defeating Teratomo and getting the good ending) took me 3 hours and 42 minutes. A bit tight, but still adequate. If you're in OGM, and manage this, you should also get the OGM co-op or single-player version of the Achievement as well.

EDIT: I've now completed an actual OGM run of the game. The only significant difference is:

1. I moved the Field Explorer 2 activity up to the beginning of the game (well, as close to the beginning as possible). In OGM, since I HAVE to fight Teratomo, I'd HAVE to upgrade my weapons more. Plus, doing that up-front would shorten any fights along the way and save time.
   
2. In the Remaining Fuel section, instead of getting the last fuel from under the Pillars of Xzorgana island, I got it from the Festering Chasm location. That's MUCH easier to do and saves me a life (since I kept dying trying to get the other one).
