The best way to get the badge is to choose the mazey map and turn of demons. Than you fight till you got fake walls and then place them so only one row of zombies can come out. Than you stand in front of that row, put something on your space bar and leave. Badge is yours.
to get everything really fast do mazey. kill them until u get fake walls. build 3 of them at the first turn.shoot through the one thats not there and viola, uv got everything and pretty soon the badge
On the second level go to the ladder then go to your right(Keep doing this so when you go far enough you will float in the air so the zombies cant get you IT REALLY WORKS(No Scam) So you can just sit back and relax while they struggle >:P(This is true it has been done by Alphavampe(A.K.A:the awsome guy)It seriously works TRY IT SEE IF I'M TELLING A LIE OR NOT! repast if this gets close to bottom please
