Halo 3: ODST (Xbox 360)

In HALO 3: ODST, a futuristic sci-fi shooter that takes place between the events of Halo 2 and Halo 3, players take on the role of an Orbital Drop Shock Trooper, part of an elite group of space marines dropped into hostile areas. This time you're deployed to Earth, in the African port city of New Mombasa, to ward off an invasion from the nasty Covenant alien race and find out the motivation for their invasion. While the action is still seen from an immersive first-person perspective, Halo 3: ODST is more of a close-quartered game than previous adventures, with much of the fighting taking place in smaller urban spaces, and focuses heavily on cooperative tactics with your ODST teammates (nicknamed "Helljumpers") rather than destroying aliens by yourself.

Though the single-player story is a relatively short 8-hour campaign, the game-play is intense and worth playing multiple times. The new Heads-Up Display (HUD) gives players lots of info on their surroundings, plus new weapons, maps, and some surprises make this game a memorable one. But Halo 3: ODST also introduces the awesome "Firefight" mode, a new cooperative multiplayer option where up to four ODST fighters can take on increasingly challenging waves of Covenant invaders. Also included in the box is a second DVD with three new Halo 3 multiplayer maps for online play (via the Xbox Live service), as well as all original Halo 3 maps and downloadable map packs, totalling 24 in all.

Online interaction: The game is even more fun when you add online friends, but as with past Halo games, you might hear cursing from other players in your headset. This is true for most online games, and many Halo players use the headsets to talk tactics while working together as soldiers towards a common goal.
