Hey,
To whoever played Command and Conquer Renegade’s Multiplayer gametype and who didn’t(Go check it out). It would fit perfectly Halo, a big team gametype which involves you buying vehicles to destroy the structures of the opponent’s base.
There are tons of vehicles that could be implemented in this game, since they already exist in halo’s universe.
Before you start bashing me I know that this “stealing” ideas from other games but, there is no such thing as true “original”, everything is an adaptation of something else.
