When looking at some missions that use XL I've seen some special features I don't quite know how they work (or if XL is behaving correctly). So I have two quick questions here that I'd like a response to:

1) How do I activate/deactivate bullet time (how do I set a key binding)? Also after using slow motion or bullet time, the music for whatever level I'm on keeps playing no matter what I do (even if I leave the mission). Do you have this issue too?

2) In Dimensional Intersect, this seems to only happen playing the 'split' (polylevel) version, but in that version, every time I exit a 'world', I re-enter the hub in the same state I was previously at when I last left the hub, rather than the state I left the world at (so I lose any reward!). Do you know how to fix this or if it's intentional? Or is the version bugged and I should not use the split version of DI?

1) To be able to use bullet time and slow motion you need two special powerups you need to pick up. If you haven't yet entered a level of the mission which contains these powerups, you cannot use these features. Both powerups also consume a lot of energy, so your energy level must be high enough to be able to use them.

2) What kind of rewards are you losing when re-entering the central hub?

It would be a good idea to register on the D2X-XL forum and ask there for help regarding D2X-XL.
