Hi Allan, i just beat the Zombie house map, but i have found a bugg in it. Some weapons have endless ammo resp. fuel.For example - when i find hunting riffle i have used it every round in the game and it was never empty.
With chainsaw, situation is little bit different:when i use chainsaw and after few rounds i am out of fuel, tinn of gass do its job and i can use chainsaw again - but with endless fuel to. Flamethrower has not such a bugg, even after filling it full with another tinn of gas after the few rounds it was empty.
