FY_SHAHMAT is the map you've been waiting for!!
That is if you want to play a game of chess in Counter-Strike!
That's right. The map's chess board and chess pieces are fully functional for a game of chess.
The pieces are all pushable and breakable and easy to differ one from another. The map can hold up to 22 players: 1 ct to control the white army, 1 t to control the black army and the rest are audience that can help their teammate or just watch the game. There's even a promotion system that you can use to promote your pawns into rooks and queens or whatever. You can use the same to get a spare piece that you've accidentally destroyed. For more info read the text in the choose team menu.
Have fun!
p.s. I'd made gorgeous looking pieces that took me 1 week to build, but due to limitations of the old engine, I had to make them simpler :( You can see how they were going to look like in one of the pics.
