I'll add a link below that links to Major Nelsons news about the new map pack for Gears 3. It contains 3 Horde/Beast focused maps that are available only for play in these modes...unless you want to play in private VS matches. I would like to say that I love Horde mode in this game more than anything but with the combination of releasing 3 maps that are on disc along with the inability to play these in TDM, Ring Leader, and really any mode other than Horde or Beast makes me really frustrated.
On the plus side it is only 800 MS Points so I am just another person bitching about DLC but they seem to have half-assed this one just to fill their quota of 4 DLCs. I'd rather they fix the fact that I get a ranked disconnect every time I quit or the host leaves in a non-ranked (as there is no other type) Horde or Beast mode match.
