@ people who think inf. ammo is a bug
when you max upgrade your gun's ammo, you get inf ammo, i tested it with uzi and magnum without using rage. they had inf ammo. its not a bug.
Fun, but repetitive, too easy to just run around in circles (i did that every wave) to avoid zombies and bosses. bosses are way too easy, all they are is just melee, make the first and second boss have a medium range attack, that would make it A LOT harder, and help combat the run in circles tactic.
