That addition of map location names by the radar I think is a godsend. Now there'll be a set naming convention so people are able to communicate field reports a lot more fluently


The jetpack thing...is different. I'll wait until the beta to voice any opinions.


Active Roster may be some kind of game balancing thing. Where you'll have say half of the players actually battling, then the other half on stand by waiting to take a fallen player's place or to play the next round. I guess it's Hockey for Halo. H4H!


Invasion looks to be a faced paced game type where one team may be given a shit load of vehicles and weapons while the others hold a position against those armaments of the apposing team.


Basically, they've taken some pretty abstract game types and further defined them into new branches without making them too map specific (like making some game type that really only works on say Valhalla but no where else). Headhunter has been in the works (as far as game code wise) since at least Halo 2. I think invasion was also in development during Halo 3.
