Two heavyweight titles have today been added to the Xbox LIVE Games on Demand digital download service in the form of Capcom’s Street Fighter IV, and Microsoft’s own Halo Wars, while Japanese Xbox 360 gamers can enjoy the top-down scrolling shooter, Shooting Love 200X.

Head on down below for a trot down memory lane, with a bunch of legacy trailers, refresher-course information snippets, and to find out how much these beauties will cost:

Street Fighter IV is a smashing revival of a tremendous series, and it’s described thus:

“Capcom’s world renowned hit fighting series returns after a 10 year hiatus! Step into the ring with familiar characters like Ryu and Chun-Li or try your hand at brand new, never before seen fighters!

“Jump straight into online matches directly from Arcade Mode with an all new online system that mimics the feel of the arcade by allowing other players to challenge you in real time. Show the world what kind of warrior you are!”

Hmm, that’s not quite good enough… you should probably read El33tonline’s review of Street Fighter IV for some more information, and check your region’s pricing over here, before proceeding to watch some great trailers for the game from last year to get you pumped:

Designed from the ground up for the Xbox 360, Halo Wars let you effortlessly command powerful armies in epic battles.”

Last but not least is a crazy top-down scrolling shooter called Shooting Love 200X, which looks as though it comprises a few different shooters in one. It’s only available in Japan though, so watch the trailer with jealousy and longing below:
