I've read a lot of the old posts here about "respawn" and I read the "Respawn Tutorial" that's hosted here.
I play a mission pack called City Battles Co-op Pack. It's got 3 nice co-op missions taking place in Paraiso, Dolores and Ortego. IIRC, there are several squads set to "playable". I just pick the Team Leader in the first squad when starting.
Respawn is set to "Group" in these missions. When I'm killed, if there are AI players still left in my squad, I respawn into one of them. But if I'm the last one alive in my group and I die, I get the seagull animation and then the mission ends.
I really like this method and would like to incorporate it into missions as I encounter them and edit them. I looked at the pbo files and there's absolutely nothing tricky in them regarding respawn - it's simply set to "Group" - that's it.
I've tried to emulate this behavior where you become the seagull if you die as the last person in your group but have never been able to. I can't stand the default behavior where the "continue" panel comes up and actually cuts off the enemy gun sound (that killed you). And if you're new to the game, you're sitting there thinking "what the hell just happened?". IMHO, that's the worst end-of-mission behavior I've ever seen in a game.
Has anyone seen this "seagull behavior" before? Maybe if I make some other squads and set them to playable I would get the desired effect? I've only see this happen in the City Battles Co-op Pack and, I think, that's all.
I just re-read my post and thought, how does the seagull appear in the first place if Respawn is set to "group"? I really wish I knew what was going on.
