That could be the centre of a new gametype, or a variant of team king of the hill. If you ever played Battlefield Bad Company online you will know how hard the fight is over artillery a lot of the time - we could have this with Halo, if in the centre of the map a control station was placed which allowed intermittent MAC salvos to be fired by the player garrisoning it. I say this rather than just supporting the idea as it could break certain gametypes - CTF for example - as people go for the MAC rather than the flag. [Edited on 12.15.2009 10:55 AM PST]
