- Red ammo. If you interrupt reloading a little earlier (release the reload button), then for a short time you will receive INFINITE ammo for ANY weapon

- Parrying. Yep, the squirrel can parry. When a person hits you with a hand/foot or a rocket, if you press LMB in time, the squirrel will parry the blow or ride the rocket. Things that can be parried are shown by a special sight/mark

- Stealing. If a squirrel climbs onto a person and a special sight/mark appears on the person in different places (as in the case of parrying), then you can steal something. Get closer to the specified place, and press LMB

- Turn on slow time to throw back enemies and objects nearby. You can also do this several times, i.e. the first time you knock down enemies, and immediately using the second time - throw back the enemy's weapon

- You can ride not only water skis, but also the boat itself.
* And when riding water skis, it is best to pick up speed, enter the aiming mode so that the boat itself maintains the trajectory and you just have to slightly tilt the skis where you need to

- If you steal a citizen's phone, then by pressing LMB on the road you will call a car (a car will be drawn on the phone). And if you are NOT on the road, you will be able to read funny facts (brilliant) about squirrels (the phone will have a normal interface)

- When driving ANY vehicle, you can press LMB to shoot backwards and accelerate.
* It is best to use smg for this
* It's better NOT to do this when water skiing

- When using the SMG, enter the aiming mode and go back and start shooting forward to move back very quickly.
*Must have when fighting Ratatskor

-It's better to defeat Ratatskor several times to get different versions of the skins. And the fights will be slightly different (at least in colors, and it seemed to me that the boss began to move faster)

- If you take something in your hands, then when you fall into the water you will go to the bottom

- Each bullet is an object. And this can be used when jumping. When jumping with a weapon over enemies/objects, you basically just shoot them.
*In the fight with Father, you can thus shoot into the hole from the tank's hatch instead of throwing grenades there, which are on the back of the tank's turret
*In the fight with Ratatskor, this is the best way to block the balls that fly at you after you end up in the air after another finishing move

-After jumping off the quadcopter, you can jump back onto it for some time by pressing E (you will jump in the air and the copter will fly up to you)

- Haircuts for people (needed for achievements).While on a quadcopter, you can cut people's hair by colliding with their heads

- Photo filters and the ability to collect them will only open after unlocking the photo mode
* To unlock the photo mode, you need to take the phone from a citizen for the first time

- Collecting nuts heals you

- While on any vehicle you can throw or PICK UP objects, including weapons

- There are electricity cans on the power lines. They can be knocked down (not only with weapons). Reinforced cans need to be knocked down with explosive weapons

- White bushes with flowers give nuts, and red ones give a weapon reload

- All kinds of vases and flower pots can be broken to get nuts
* Almost all glass, by the way, also breaks

- You can destroy haystacks with explosive weapons or by FALLING into them (hello, Assassin's Creed). Nuts fall from them

- Flagpoles show in which direction which collectables

- You can throw all sorts of things at enemies, including weapons

- I'm tired of writing this

- And most importantly, squirrels are cute ːsadcattivaː

That seems to be all that came to mind. Write, maybe I missed something interesting
