I just LOVE this game even the first level is fun!
The music is awsome too.
The cool thing is on the 1st level there no teddy bear in the treasure chest (it makes it move somewhere else)
You start with a colt 45. and the first weapon you can buy is a Kar98k (Points listed)
Theres lots of windows you have to protect, try to build them when theres no zombies around.
1st level unlocks:
HELL door= 1000pts
Upstairs=1000pts
Treasure chest=950pts
Thompson= 1600 (i think)
DB shotgun= 1600
Kar98k=200pts
M1 carbine=600pts
Barriers=free :D
And more.
I'll get a pic:
