Then hit start and you should begin a game. It is going to be player 1 or 2 that wins then check your challenge list and there should be a star on the second place on the challenge that you chose.
Playing in Multi-player mode
In Multi-player mode keep moving standing still makes you an easy target for automatic weapons.When playing against sims Meat, Easy, or Normal varieties, shoot weapons and ammo boxes out of their normal respawn locations then collect them. The weapon or ammo will respawn where you picked it up. Simulants will think that it has been picked up and pass it by without looking. When with your back to a corner and low health, arm a grenade or n-bomb by holding Z. Run at your opponent there is a chance you can also kill him. When using cloaking devices, go for easy kills by using combat knives. Slashing with the knives will allow you to stay cloaked and give you a chance to get in some damage.
Opposite Reactions in the Carrington Institute
When your inside the Carrington Institute, find a way to punch with "Z". There are couple of ways to do it. Then go up to one of the opponents and hit him/her in the BACK. Then take a look at their reaction. They will move back instead of foward.
