The game of Derka is rather simple. Here are the rules:
1) Must use grenades only
2) Must type "DERKA" when you get a kill
Heres how you play:
1) Take out a grenade
2) Go to the enemy spawn
3) Look for a victim (enemy)
4) When you get to the enemy spawn, hold the grenade for 2 seconds, and throw it at the ground near an enemy.
5) Kill yourself with the grenade and kill the enemy.
6) Yell "DERKA"
Thats how you play the game of Derka. Have fun.
P.S. Here is a link that you can save as your grenade sound so when you pull the pin on a grenade, it goes "ALLALLALLALLALLALLA" http://dl.dropbox.com/u/31711941/derka.wav
