I changed my host so it downloads ALOT faster. It is a 3 map/part Half-Life 2 single player level. The player must infiltrate a combine Lab in the city. PLEASE DO NOT JUDGE UNTIL YOU HAVE PLAYED THROUGH THE WHOLE THING! Also, don't use cheats; play through it normally!
The first map is figuring out how to get to the end. The second map is full of puzzles and obstacles that the player must navigate through. And the third map is more of fighting enemies.
