Did I mention I charge £3000 per idea? No? Damn, I guess I'll let you off this time...
I did have a slightly 'odd' idea for the rescued people, which might just be stupid, or could make for a tactical, 'puzzley' type take on the game (maybe suited to the slower pace of the game). Basically, the people you rescue would follow you like the game 'snake'...so there'd be a big chain of them, following your exact footsteps, and they wouldn't get out the way so you could shoot them accidentally (or deliberately if they box you in).
Does that make sense?
It might not be compatible with the view and the 'torchlight' style of the game though, since you wouldn't be able to see the 'queue' most of the time. or maybe that would make it more tense as you'd have to keep looking back at them...Another
twist on the rescue angle...rescued people will follow you in a more general way, but they'll only move while you have the torch shining on them. if you leave them in the dark they'll just stand still terrified. that way you need to balance looking at them to keep them moving, and looking for zombies!
anyway, I think i've muddied these waters enough for now!
I was thinking of making a "safe house", like hospital or something and you go on search mission and have to take people back to that place.. maybe have some guards at the entrance that shoot at zombies from the gates.
The followers would be as you said in "snake" formation, however only in the direction you are moving, not your angle.. so you could look at them and defend. Of course you can shoot them if you wan't!
