PlayStation Magazine has published some interesting information that we thought we would pass along. Rockstar has had their dev kit since August and is working on a new game engine for next-gen GTA titles. The landscape of GTA 4 is a photo-realistic city with advanced AI for NPC.
PSM has also given us some tidbits on Metal Gear Solid 4. Snake is fighting alongside computer-controlled soldiers in a urban environment that has been destroyed by war. There will be a large presence of projectile weapons (hence the slogan "No place to hide").
