Bringing back the "classic" infection mode that made halo 3 custom games so fun would be a smart and respectable move for 343 (assuming they do it soon). I remember getting Halo 3 and playing very competitively for about a month. Then I got bored of matchmaking and became a forge/custom games player when the map packs came out. I like creating modes like predator and fat kid. If 343 is stuck on flood mode for matchmaking and the flood having classes to choose from (since apparently they are a very intelligent species that have armor abilities), they can keep that mode but at least bring back the old infection game type for custom games. I like halo 4 and have been a fan since the first halo, but 343 seems to have overlooked what people wanted from the forge/custom games fanbase. I played twice as many custom games than matchmade ones in halo 3 because the variety of custom games kept me playing the game even after having it for several years, and I want to do that for halo 4 as well.
