You are probably reading this to learn how to play :) It's simple, use the mouse to control your cursor, left-click to interact with buttons, use S P A C E to fire your machine gun, and remember, you can only earn up to 1000 Marks (the German currency). This is where it gets fun: to use binos in phase 3 and beyond, press W, wait for the cursor to acquire the target, and enjoy the fireworks. Buy better equipment with Marks, defend the trenches from waves of attack, and try to reach the last wave! Good luck!
Over There is loosely based on the First World War. According to the scratch team, this game may be too violent... Thanks to @HippoLimbo for several menu assets and the beautiful weapon models!
