Do you know that they're selling the game (pre-order) in order to pay for making the game? btw, if you like this play running man, it's the next demo and it lets you move and shoot at different kind of robot test-dummy's running at you
NOW i see why my teacher made me learn every single country and position and then tested me 4 times in a year. so i could get a tiny medal on kongregate to enhance my self-esteem. i can get you the right country, and then its random clicking.
chainsaw? rocket launcher? who needs all that crap. any true zombie-slayer knows that all you need to survive zombie apocalypse is a good old-fashioned shotgun. preferably pump-action. and, ofcourse, infinite ammo or you'll be looking pretty stupid trying to club zombies to death with an empty shotgun
to solve the 4 rooms puzle write down every text you find the way you find it. whether you leave the room trough the left or the right will change which rooms you enter(tis may sound confusing but youll get the idea). theres is a paper in every room. if you have them all and still cant figure it out, look at the numbers. read the top word from the first paper, then the second, then the third etc. and youll get the instructions. for the rest, simply do what it tells you to.
if you really need to you can find a walktrough online, but generally you need to know this: the keypad number is 1904(the first time minus the second) and for the rest you need to have patience,and repeat yourself. alot.
