StarCraft 2: Brutal Co-Op Edition - Lock and Load as Tychus (Mutation: Time Lock) 

Playing Lock and Load as Tychus with the Lone Wolf prestige, while my co-op buddy play as Stukov with the Infested Admiral prestige.
Mutation: Time Lock
Time Warp - Enemy Time Warps are periodically deployed throughout the map.
Speed Freaks - Enemy units have double their normal movement speed.
Mag-Nificent - Mag Mines are deployed throughout the map at the start of the mission.
TIP:
Tychus P2 can evade mag-mines and dealing fast moving enemies, while your ally are cannon fodder for mines, so be quick about it.
