Basically we have a Fallout stripped of everything but the combat system, with graphisms recycled from an other game and a furry as character? IS there even a point in that ? Not to forget the mechanism relies mostly on luck.
The game is not finished to me : it's pointless to continue pass 4th boss as waves are the same after ( I reached 34) . Big choice of weapons but in the end I only used uzi fully upgrade and gatling , so pointless to have an impressive choice. Weapons can be changed by using the mouse wheel, but then the game window scrolls : very annoying. Also always starting with the most expensive weapon you have is a pain ( I bough chainsaw for the fun, but use the gatling ). Last problem, the ammo :if you happen to have used your full stock, you're start again with 200, which is a joke when using a gatling or a chainsaw. You should : allow to buy ammo even over 500 or allow to buy upgrades increasing the starting ammo amount ( maybe health bar upgrades also ? ).
Other than that, it was fun.
I was tempted to scream like that too, given I kept losing at first (8or 9 loss in a row sure isn't fun). Then I won a match, and even 2 in a row, last with a margin of 5100. It's just a real matter of luck, maybe too much for some people.
The shotgun is the only really useful weapon I can see : grenade gun and alien weapon have just one ammo, sniper rifle is slow, assault rifle long to reload, and the minigun didn't shoot....
