GG_nuketown a CS:S Gun Game map based on the Call of Duty Black Ops map with the same name. It is not a complete remake, as the interiors of the houses are different, but its layout and overall feel is about the same.
Within the first minute of each round, an airplane will drop a care package somewhere in the center of the map. These care packages serve as a way to bring people to the middle of the arena for more frantic gameplay. The first player to open the care package will be given a randomly chosen reward. The crates contain special grenades (2 flashbangs and a smoke grenade), an airstrike that obliterates the opposing team, and the ability to man a helicopter's minigun turret. While these do not count toward your own score, they will bring your victims down 1 level (in Gun Game) each time they die.
I sure haven't posted here in a while... To be honest, I didn't put much effort into this map. It's still fun, but doesn't look that great. Most CS:S players are used to poo-poo maps, so I figured why bother? Oh and, don't try to build a .nav file. It crashes the game.
