The latest DLC to U2: Among thieves provides the new online option "Invasion" which is like Halo 3: ODST and Gears of War Firefight/Horde mode. The biggest twist i changing location on the map to different ones forcing the party to move. This offers a fun session of teamwork and gameplay which can make you enjoy yourself. This also brings two extra maps for multiplayer for you to run around and shoot stuff on. Worth checking out? I'd say so.
