If you're a fan of stealth games or cannot wait for the next spy vs merc mode in SC: Blacklist, then this should be an automatic download for you.

The gametype is called Spec Ops. It can be played 1v1, 2v1, or 2v2. When playing 2v2, if the merc dies he spawns as a spy but cant move cause he's considered dead. This game took me 1 month to make. Mostly from balancing the gameplay.

-1 custom powerup(radar enhanced for 5 sec, and waypoint: visible to everyone)

Notes:
-This has nothing to do with zombies
-Spy: don't use your weapon to kill, run away from the red waypoint, and running takes ur camo away
-Merc: back against the wall and dont camp or you will die in no time

Spec Ops v3: This might be a better version but Im not sure. Im trying to make this a newb friendly game w/o it being bad, so the spies have a sniper and sword. The sword takes 2 hits to kill and the sniper does the same damage as the H3 BR, which is 3 shots in the body and 1 in the head, so it's gonna take teamwork to snipe a merc.
