1 - can an entire level be tilted or rotated during runtime...
NO.
2- is there a provision for multiple floors in a level...
YES, can be done easily. A level is 40x40 tiles large and can have up to 20 floors.
3- i've seen helicopters in scenes... can these be moved around the sky like real choppers...
YES, but you need to script realistic movement. But, the player cannot enter or fly them.
4- can players characters be attached to these things as they move around.
YES, but..... You can have moving platforms (up/down or left/right/forward/backward), so in theory it could be done, but it will not be easy achieved.
5- multiplayer... how many players can play in a single game...
8 players
6- can multiplayer be played over multiple level games...
No, it's an Arena style game, so one level only.
Multiplayer games do have a few restrictions:
- No physics on entities.
- No dynamic entities except weapons, ammoand health.
- All dynamic entities not essential to gameplay are forced to static.
- No projectile weaponry (rocket launchers, grenades).
- Only one level per arena executable.
By the way Mike, are you the same Red Ocktober as the one on the 3DGS forums? I'm pretty sure you are. Are you still working on the submarine game? If yes, you need to know that FPSC isn't as advanced as 3DGS A6. FPSC is really cool and easy to use, yet powerful in what can be achieved. But you need to be inventive and have to work with (and around) the limits FPSC does have.
You may recall me, I've been working on a game called Commander Josh in A6, but due to a number of bugs and the lack of a new update for way to long, I was forced to stop creating it. I'm working on non gaming projects now with FPSC, but I've started to work on a revived version of Commander Josh also, I've called it Mars Take Over for now.
Even though FPSC isn't as advanced as 3DGS A6, but when it comes to creating a FPS-like game, I think FPSC has a number of advantages over A6. You may not see the most brilliant projects around here as you do see at the 3DGS forums, although there are some excellent project in development. There are a lot of first timers and kids around here and that shows at times. But... if FPSC is placed into the hands of a more experienced and capable game designer, a stunning game could be created.
