The thing to bear in mind is that only a limited number of functions can presumably be assigned to any of the console ports this game will be released on.
In all, a Xbox 360 controller has 15 buttons, the ‘Y’ ‘X’ ‘A’ ‘B’ buttons which presumably would be set to choose whether you have the PKE, Proton Gun, Trap or ‘no weapon selected’. The two triggers, one of which presumably is the regular Proton Beam when using the Proton Gun, and the other is the ‘knockout’, the ‘surge’ which is said to be a part of the Proton Beam to allow you to weaken and entity.
Of course, the R1, R2, L1 and L2 may be there for for weapon options as well… whilst certainly the directional stick and arrow buttons are self explanatory.
I'm sure we'd love to be able to emulate every element of the films, communication via radio, throw out a Trap whilst firing and other elements seen in the films… but there's only so much that can be achieved with a console gamepad as at the end of it, everyone has to be able to play the game and futhermore… it has to be fun, if it ended up having difficult combinations of options it'd probably discourage people from playing it…
