The new Gears 2 DLC comes in two flavors: 7 new maps (featuring some classic remakes) and a deleted bonus scene single-player level for $15, or all that *PLUS* all previous DLC (19 multiplayer maps total) for $20.
This is a good chance to bring together the multiplayer community. For $20 you can get everything and be up to date with everyone else.
It’s a shame I remember the days when Epic would release 200 community map packs as a patch.
