i got some cool ideas for halo 2...
1. the pelican dropship is playable in multiplayer only, one person flys,one person fires the "chin gun" and it can carrie 6 other players.
2. judging by the trailer
http://www2.mythica.org/halo/hbo/hal..._qt6_large.mov the first level should be on a covenant ship.
3. the flood should return...
4. the forerunner should be introduced.
5. there should be 4 types of granades.
6. MC should keep the 2 weapons only thing, its more realistic.
any more?
