As promised, Koei’s oft-delayed futuristic racer Fatal Inertia EX finally makes its debut on the PlayStation Store this week, complete with tweaked controls and extra levels not found in the original 360 retail release.

In addition to the launch of recently announced Metal Gear Solid 4 knowledge database, add-on content this week is comprised of an Oceania course for PS3 title Hot Shots Golf: Out Of Bounds, along with a Coldplay track pack for Guitar Hero III, free The Incredible Hulk bonus content, and the usual round of Rock Band songs.

Looking for some new games to try out? This week’s update is packed to the brim with playable demos for NCAA Football 09, Wolf of the Battlefield: Commando 3, Hail to the Chimp, and the just released Fatal Inertia EX.

That about wraps up this week’s round of offerings, apart from PSP UMD title Gurumin: A Monstrous Adventure, which is now available for digital purchase on the store. Not too shabby of an update, by my standards anyway.
