"DBNO (Down, But Not Out) is featured in the Gears of War: Judgment campaign. As for competitive and co-op multiplayer, a DBNO-like feature exists in OverRun, wherein the Medic class has the ability to revive teammates who are downed with our new stim grenade. The difference is they are stationary and are not crawling around. Grenadiers on the Locust side can go DBNO and then be revived by another Grenadier or a Kantus," Epic informed Joystiq. "And for obvious reasons, our new Free-For-All mode doesn't feature any sort of DBNO. We have more modes to announce in the future, so we can only comment on the modes we've announced so far."
The fact that the company won't comment on modes it hasn't officially announced yet is what is complicating this issue. During our visit last week, the company wouldn't acknowledge Horde mode was part of Judgment either. Gears fans will have to take a "wait and see" approach to what's actually going on, since Epic doesn't want to deviate from the marketing plan.
