Co-op Missions

Were you looking for Cooperative Play, the mode in which more than one person plays through the campaign at once?

The co-op missions are 5 different levels in Halo: Spartan Assault on Xbox. They are not available on the Windows version. These missions are designed for cooperative play, and thus cannot be played with only one player. None of the events in this mission actually happened, as these are simply UNSC training simulations in case the flood should return.

Missions

 * Co-op 1: Checkpoint
 * Co-op 2: Holding the Fort
 * Co-op 3: Structural Integrity
 * Co-op 4: Transmission Interrupted
 * Co-op 5: Power Net

Exclusive Weapons
These missions contain new weapons and armor abilities exclusively for these missions.

M6 Machine Pistol
Serving a similar purpose to the SMG, these weapons are only found in pairs in Halo Spartan Assault. They seem to be far less accurate, and have less ammo, but fire much faster. Rounds fired by this gun do not travel very far, making it a mainly CQC weapon. The weapon is extremely useful for dealing with hordes of infection forms

Repel
This armour ability when used creates a circular area into which the flood will not enter. This area centres around the point where the player first used it.

Teleport
This armour ability teleports the user to their ally across any distance on the map. Interestingly, if said ally has died, use of the ability teleports the user to the body.
