Have to crouch to pick up drops; picking up a gun of the same ammo as one you already have will automatically transfer it to the one you had first, dogs don't drop max ammo sometimes (don't know if its intentional), doesn't cost extra money to replinsh ammo after pack-a-punch, lunge melee sometimes teleports you through zombies, overall great potential, gunplay is fun and it feels great just some bugs and stuff I noticed
