I thought suddent death kicks after Raiders run out of 16+12+8=36 lives. However, it kicks in after 16+12, and the raiders fail the mission when the last 8 lives are depleted.
In anyway, Sudden Death is ok to me, and it is a part of "team-up or die" concept, but it needs some adjustment.
MSE better to add some incentive for the raiders to gather around.
- Activate short wounded time if your team mate is in the proximity, say 8m.
or
- Revert the wounded time back to 5.5sec.
Recover the wounded raider when non-wounded team mate get closer. Say, 25% chance to recover from wounded when your team run towards you at 8m distance, and 75% chance when your team is at 5m distance.
(Wow, Herec leader can rescue people)
