This is not the half-life 2 mod! Instead, it is a simple game in game maker that I made as a test, pretty much! It has doom weapons and enemies as well as sound effects. Made in the reloaded engine, it is not terribly simplistic. DISCLAIMER: When I made this (2011) I was unaware of the Half-Life mod!
