Critics are a bunch of daffodils.
Yes, the inability to carry more than a single clip in a single gun was annoying. But don't listen to those losers whining about the difficulty. If you don't like using the sword, freakin AIM! Don't get another gun until you can't finish the next wave with your remaining ammo! If you can kill multiple enemies with a grenade, DO IT! Don't waste any ammo on those spider things! KILL THOSE GODDAMN FLAMETHROWER GUYS FIRST, and when you do, DON'T just mash on the trigger! Stay calm and fire 1 or 2 shots at a time, or you'll miss, run out of ammo, and get fried. I figured this stuff out in two minutes, and I get to around wave 30 every time, which I think is not too bad.
Over all, a very good game once you adapt to its quirks. It's like a lunch break sized Crimsonland. Then again, Crimsonland is lunch break sized, so this is probably cigarette break sized. Don't change the difficulty, and don't change the blood! That has so much more style than a life bar. And really, shouldn't things get harder after you've got 3rd degree burns and a tank shell stuck in your leg?
My only real gripe is that I can't figure out what those numbers mean at the end. The ones like "You've killed 728 tons of radio shack equipment" or something. I don't get it. But whatever. Good game.
