In Tri-achnid you play as an endangered species of exopod on the verge of extinction. In search of a safe haven for his young the tri-achnid must fight his way out of the lithic alps by any means necessary.
You are Sergeant Sokolov, a Soviet soldier taking part in the Battle of Stalingrad in 1942. Your objective is to purge the city from the invading fascists. Make use of the reinforcements at your disposal (officer, infantry, machinegunner, mortar team) to defeat the enemy!
Select the number of players and level to start the game. Blow up your opponents using bombs before they manage to kill you. Destroy blocks to leave behind power-ups which will give you special abilities when picked up. Each player has three lives so they will need to be killed three times to be eliminated. There is a 3-minute time limit in place. If you win a game, you will score the number of seconds remaining on the timer multiplied by 250, times the number of opponents in the game. Losing a game will result in that amount of points being subtracted from your score
