Starting in June, Ubisoft and developer GRIN will release brand new multiplayer modes, including:
* Deathmatch mode, Map Editor for Deathmatch and Domination, anti-cheat fixes, Anti Aliasing feature, and New co-op maps
Throughout the summer:
* Team Deathmatch, Hamburger Hill modes, Original GR co-op mode, Map editor for TDM, HH, OGR co-op, GRAW co-op improvement (quick start and respawn) and Dedicated Server pack
I don't see how else to interpret "original GR coop mode" other than "the way it worked in GR". Since the leader dying made no difference in GR, I'm interpreting this to mean it will be the same here. Now the player limit I'm not so certain about, merely because player limits are usually considered separate from game modes. I'm still hopeful, though.
The respawns I would also interpret to include the leader. If not, I can only say they've not been clear enough with their intent vs how people would read it.
