You can use Blender, Milkshape, Fragmotion, 3D Studio Max, etc. Just about
any software application that supports animation will work just fine. The reason animated cutscenes aren't seen to often (if at all) in the WIP board is because the amount of work involved, for those that actually have the skill to pull it off, just isn't worth the effort for a 15 minute game.
Quote: "I mean like having a Chainsaw Brute roar, kick down a door and cut a guy in half or something. "
You would need to import all of those characters and entity meshes (the Chainsaw Brute, the door, the guy, etc) into your animation program. It would also be helpful if you were to load the actual area this scene will be taking place in as well, (walls, etc); so you don't create the animations to play through a static object. Then, start creating your animation sequences;
1. Chainsaw brute roars.
2. Chainsaw brute moves forward (default animation), and slashes chainsaw down.
3. Door crumbles into pieces.
4. Chainsaw brute moves foward(default animation) toward the 'guy'
5. Chainsaw brute raises chainsaw and brings it down on guy
6. Guy gets sliced in half.
*(The alternative to the above method, of course; is simply working on each entities' animations one at a time, and putting them all together in FPS Creator.)
Once all of those animations are accounted for, you can either link them together or have them play individually using scripts and triggers in-game to call them. Then you can spin the camera (the player-position) around the action as it happens; looping the animations so the action repeats, and you can capture various views of the scene playing out. Then, import you capture into a video editing program, break it up, piece together various camera views, add in effects; sounds, music, etc. And, you have a cutscene
