I had a few games on it and it's actually really fun! It really set's apart the noobs from the elites. No kill streaks. No HUD. But excessive camping....but if you're not a noob and don't do that then Maximum team is sick! I mean sure at first I was like "yea wtf no HUD whats the point then if you can't manage your suit like you're suppose too, and what's with these campers?" but it means that the noobs REALLY struggle and just sit there or run in the open, and with the lack of HUD you are forced to look out for them more than just stare at your non existent mini-map the whole time. PLUS less BS because you're the one dealing the damage and the damage dealt is brutal and deaths deliver fairly instantly to any weapon, so less potential damage sponging and the usual BS crysis suffers from. Also the lack of HUD you notice just how good looking the game is without 20% of your screen full of energy read out's and ammo reserves. Haven't lost a game on it so far, but you don't get that many kills as a lot of enemies tend to cower away but aren't that much of threat to flush out.
This mode works loads better than TDM, like you said less sponging, ive been playing MTDM since day one and havent really stepped foot in normal TDM after seeing how some of these players lag into invincible mode
