AKS-74U

The AKS-74U is a weapon in Brain/Out

Background
A variant of the AK-74, developed alongside it to better suit aerial infantry. Has a side-folded shoulder stock instead of the AK-74's wooden one, made from stamped sheets of metal. The stock is triangular in shape, making it much tougher than the somewhat fragile under-folded stock of the AKMS. Ideal for close quarters fighting, though it is often criticised for its blinding muzzle blast and high full-auto recoil.

How to obtain
Available at the start by default

Tactics
as this weapon is granted to the player at the beginning of the game, it is outdone by almost all of the weapons that come after it.

on the bright side this weapon has a higher fire rate then the next two weapons to be unlocked.
