So many fights, so many casualties. Different kinds of soldiers were doing Special Operations to fight for important resources that were coming to an end. One would die, and someone else would be born to replace him. Now many ordinary people build or find their armored suits, rifles and equipment just to save themselves. Some fight with metal pipes, some fight with Laser Rifles. You never kno what is gonna hit you.
Soldier - A balanced class. Better at Fast Fire weapons like AK-47 and M4A1. Soldiers are also fast, but can be easily assassinated. Good team-up with a Brute, when Brute takes the damage while the Soldier kills everyone from behind. Starts with a 9MM Pistol!
Assassin - He uses Snipers as weapons in later periods. Very high damage and stealth mode, but can die easily if he's exposed. Good for a team up when others distract enemies while he shoots them one by one. Starts with a Silenced 9MM Pistol
Brute - Double Pistol class! Uses pistols on both arms, which deal low damage, he's also not that fast, but he's very resistant and won't die easily. Good if teamed up when he takes the hit while others shoot at the back. Starts with Dual 9MM Pistols!
Tinker - Lowest attacks, lowest health, but rather creates fast structures and provides his allies with best class Rifles and equipment. Good class for a team up. Starts with a Metal Hammer!
Few Notes You can team up with any player who'd you like with. You can also be an enemy to whoever you want to. You can do this anytime. But you first have to sent him/her an Invitation through Profile comments and he/she must accept.
