Counter Strike Source
This is Genome.Soldier's first map, its mostly entirely made out of lego blocks!, its pretty neat.. have fun!
Here's a map in which players jump around small blocks trying to knife each other. You get a knife and one frag grenade, and are then sent around to kill everybody on the other team.
The author already has released his first version of his ladderwars map, v2 is completely remade from the ground up.
Mostly Dark yet very fun map. THIS is a night map witch you and your team must work together IN THE DARK to kill the enemy. Sound and Light are your enemies.
An awesome map for CS:S, but be careful, if you fall in the water you only have 3 seconds to live
