Story: HL2 mod continuing story of HL:Opposing Force character Adrian Shephard in a time set somewhere between HL1 and HL2. It brings you from a Black Mesa like base trough an outdoor environment and a Soviet marine base into a early combine citadel to end in a ancient alien location here on earth, the combine stumbles upon when creating a citadel. What you get: Intro and 5 playable maps roughly good for a hour of playtime. The mod includes custom props, textures and music but NO new weapons or NPC's.

The game starts off with an intro sequence similar to that of a movie: tense music and Combine troops closing in on a base as the people inside scramble to defend it. This sequence drew me in, but after a few minutes of sitting around I got bored. The first lines of voice acting made me wince; the voice actors barely came close to the original voices of Eli, Dr. Kliener, Barney, G-Man, Judith, and Dr. Breen. (Noted that the woman in the airvent who looks like Mossman is actually named Tess, but I digress.) The gameplay was good, but got a little tense at times when, as it always seems to be in HL2 mods, I appear to take more damage than I should. The music was amazing; I can't stop playing the Kilo Base level for no other reason than the song that plays in the background. Level design and gameplay elements (puzzles and enemy location) are also a strong point in this mod. Overall, I say this is a good mod and a wealthy addition to anyone's HL2 mod collection.
