Ok at round 4 go up stairs buy doors and stay in there where the stakeout is with one person on the up up stairs and one person on each floor in stakeout room then another just running around and helping then open the next door when dogs(second wave of dogs) come lean against the theater door everyone it a glitch the open it after wave don't turn power on one person at back window then three people by where the box is checking the other window occasionally the zombies will come from the stakeout room in a strait line just pop the heads off don't go on right side by curtain because theyll run all I've (zombies) once you get over run turn power on this should be at least round 27 if your good make sure to get crawlers too bored up windows and get ammo once powers on find the mystery box don't open the stage stair door go around spread out so zombie follow one person at a time don't bunch up make rape trains buy power up when needed help each other pack a punch enjoy.
Keep moving around don't open all doors try to get thundergun then upgrade it only use that when you're in trouble Buy juggernog and quick revive Don't upgrade mp 40 just buy it's ammo for points Btw: at rounds 23- infinity and beyond use traps because your attacks get weaker and even if you upgrade it still gets weaker. P.S. Traps kill instantly.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
