These are the facts collected from IGN's interview with Terry Nagy of Apogee. Developed by Deep Silver Trilogy's parts are called Critical Mass, Chain Reaction, and Proving Grounds. Critical Mass is set in the future and will have futuristic levels & weapons. Chain Reaction is set on present day Earth, but will still have futuristic weapons. Proving Grounds is set in 1945 & has weapons to suit that period. The first game will be released Summer 2009, and each game will follow just after the one starts losing sales. The team are committed to this time slot. DS version will be a Teen rated, side scroller but you can also go into "cover-fire position", which is basically over the shoulder 3rd person. PSP version will be a mature rated and for hardcore gamers and includes third-person, first-person, top-down views but it'll have less modes than the DS version. So sadly the DS one isn't as mature (or immature, depends on how you see violence) but will have more game modes so it looks like Duke fans will need both handhelds I guess. One thing troubles me is that they are insistent on a Summer release date, I personally would rather they'd released it when it was ready, even if it takes "Forever".
