Those with Half-Life 2 should get this. It includes maps very similar to those found in the hit N64 game Goldeneye. I’m sure I don’t need to tell you how awesome that game was. Even though I initially hated this mod (I blame it on the bad map I started playing on,) this mod is clearly made of win. Some advice: This game is the most fun with a small group of players (10 max) and maps that aren’t the cave (I don’t remember its name off the top of my head). You can find out more and download the mod here.
