I'll give a short summary of what kind of achievements there are in Blockstorm and how to get them.
You can only get achievements in official servers (The servers marked in gold!)!

Description
You'll get these achievements when you have won a certain amount of matches from a certain gamemode.

➤ Each gamemode has 4 achievements: win 10, 25, 50 and 100 matches.
➤ 'Team deathmatch' is the exception here: win 25, 50,100 and 250 matches.
➤ 'Deathmatch' doesn't have specific achievements.

Team Deathmatch:

Assault:

Capture The Flag:

Castle Battle:

Hunt:


How to get these achievements
These achievements are quite easy to get by just playing a lot of Blockstorm matches, but will take a lot of time (especially for 'Castle Battle' & 'Hunt', both which aren't played much).
If you really want to get these achievements, you could try joining the winning team when you join the server or changing to the winning team later on in the match (You can't change teams in the last third of the match!).

Description
With this I mean the achievements you'll get when you've completed a gamemode objective a certain amount of times.
➤ The 'most valuable player' achievements are available in every gamemode, the other achievements are only obtainable in the gamemodes 'Capture the Flag', 'Castle Battle' and 'Hunt'.

Most valuable player:
Be the most valuable player of the match 1, 10, 50 and 100 times.


Capture the flag:
➤ There are 3 types of capture the flag achievements:
- Capturing flags (10, 25, 50 and 100 times).

- Returning flags (10, 25, 50 and 100 times).

- Capturing an amount of flags in succesion (3, 5 and 7 flags).

Tip: Use a shotgun so you can quickly capture and return flags!

Castle Battle:
➤ There are 3 types of Castle Battle achievements:
- Destroying chests (10, 25, 50 and 100 chests).

- Destroying thrones (5, 10, 25 and 50 thrones).

- Destroying an amount of chests in 1 match (3, 5 and 7 chests).

Tip: Use a M240 and explosives to easily destroy chests and thrones!

Hunt:
➤ You'll get achievements for a certain amount of 'Blocktanium atoms' you have collected (100, 250, 500 and 1000 Blocktanium atoms).

Tip: Use an automatic weapon and explosives to easily destroy 'Blocktanium pods' and kill zombie!

Description
This group of achievements is dividable in 2 subgroups:

The overall kill count:
You'll get these achievements for having killed an amount of enemies throughout the whole game (not including NPC's).
➤ The first part is below 1000 (50, 100, 250 and 500).

➤ The second part is higher than 1000 (1000, 2500, 5000, 10000).


Kill count in one match
You'll get these achievements for having killed a certain amount of enemies in 1 match (20, 30, 40, 50 and 60 kills).

Fun fact: When achievements were just introduced there were 70 and a 80 kills in 1 match achievements too, but these were removed because they were too hard to get. Nevertheless, a few people have managed to get 70 to 80 kills in 1 match.

How to get these achievements
The 'overall kill count achievements' are easy to get, but they will take you a lot of time.
The 'kill count in one match achievements', however, require some skills, and some may even seem unreachable. Using a M240 in small maps as 'Underground Duel' can ensure a lot of kills. But most of the people get these hard achievements in the Deathmatch map 'Medieval Hell'. A third possibility is to use the new (slightly overpowered) mecha's to get a lot of kills.

Description
You'll get these achievements for having killed an amount of people with a certain weapon.
This group of achievements is again dividable in 2 subgroups:

Primary Weapons
These achievements require a lot of kills (50, 100, 250 and 500 kills).
AK47

MP5

Rifle

M240

Shotgun

Sniper Rifle
This is the exception here (25, 50, 100 and 250 kills).

Knife
It's not a primary weapon, but it requires the same amount of kills as the other primary weapons (50, 100, 250 and 500 kills).


Explosives
These require less kills (10, 25, 50 and 100 kills).
C4

Claymore

RPG

Grenade
This is the exception here (25, 50, 100 and 250 kills).


How to get these achievements
Primary weapons are mostly used, so these achievements are not very hard to get, but will take a lot of time. When you use the shortcuts for Knife (E) and Grenades (G), these achievements won't be very hard to get either. C4, Claymores and RPG's achievements might seem harder to get, that's why I'm going to give a few tips.

C4
It's important when you're using C4's that they're not visible, or else someone might be destroy it before you can make a kill. Make traps, close tunnels (built by the enemy) with a block with c4 for instance. I can ensure you the first time always someone tries to open the tunnel again and die by the explosion.

Claymore
It's important when you're using Claymores, again, that they're not visible, or else someone might destroy it before you can make a kill. Destroy one of the lowest block from a wall and place a Claymore in it. Most of the people don't see the laser beam and will be killed by your Claymore.

RPG
Use as primary weapon the Shotgun, so you'll stay light and run fast, when you have made a kill with your RPG, you can quickly run to the backpack and refill your ammo. This way can make kills faster and you won't be an easy target.

Description
You'll get these achievements for having killed a certain amount of enemies within 10 seconds (3, 4 and 5 kills).


...or with one explosive (2, 3 and 4 kills).
Grenade

C4

RPG

Fun Fact: I got the '3 kills with RPG achievement' by killing 3 annoying campers in 'Abandoned City' at once!

How to get these achievements
Join a well filled match, preferably in a small map like 'Underground Duel' and use an M240 (though other weapons may be fine too) to try killing 5 people within 10 seconds. Killing multiple people with an explosive is a bit harder, especially with c4. Just try to find a spot on which frequently a large amount of enemies gather and try to use your explosives at the right moment.

Description
Finally some achievements that are hard to classify.
Your first kill!
You made the first kill of the match!
You are the first to be killed of the match!
You killed someone with the last bullet of your magazine (except sniper)!
You killed someone while he was reloading!
You killed someone with your grenade after you died!
You killed someone while you were in the air!
You killed someone while he was in the air!

You quit the match right after you died!

You have viewed the Credits page (All the way through!)!
