Six player Match making Revives on So 6 players spawn in a massive arena, enemies don't stop spawning until everyone is dead the goal being to survive as long as possible for rewards set at certain time goals(warframe survival without air pods) EDIT: No time limit, or objectives. Technically you could go forever if you were good enough. However if you don't keep consistent damage to an extent the activity will fail(prevents just running away invisible forever) EDIT: Infinite Forest could be used as a base to make this mode.
