i like highrise because you can spawn camp either side and the map layout is nice you can flank either side or go underneath and sneak up behind them and i love the spawn kill
well my favorite mw2 exclusive map would have to be hands down, rundown. its large, even amount of buildings and sniper spots between the two spawns and good locations for ground fights and ninja sneakers
i say.... well, Afghan, i got a 23 killstreak on free-for-all, too bad i didnt have AC130 equipped... and wats Carnival, and Vacant? i have not heard of those... i just got the map pack with Bailout, Salvage, and those... or, are those on Xbox 360? anyways, my second favorite is... uuuuuhh... Sub-Base
