Xbox LIVE’s Games on Demand digital download service is today two titles richer with the addition of Soulcalibur IV, while Medal of Honor: Airborne is added to more Xbox LIVE regions around the world.

These two games are as polar opposite as you can get as far as genre and content is concerned – one is a fantasy-based fighter and the other a World War II-based first-person shooter – but isn’t playing games all about expanding your horizons, and transporting you to worlds you’ll never get the chance to inhabit in real life?

Then Soulcalibur IV and Medal of Honor: Airborne are for you! You can find out all about these titles with some official descriptions and classic trailers below:

Medal of Honor: Airborne

“Take to the skies in Medal of Honor Airborne, where your choices will turn the tide of WWII. Starting with your jump from a C-47, every choice you make can seal your fate. In the air, control your parachute to select the landing spot that brings you the greatest strategic advantage.

“On the ground, explore the open, vertical environment for positions that will provide you a tactical edge against your enemies. Then, head onto Xbox LIVE for furious multiplayer battles in three different modes, including all-new Airborne modes! You decide where to drop, you decide how to fight. It’s a different war every time.”
