Tour of Duty request, eliminate field capture by airborne forces.
HT (or was it Pyro) said a long time ago that 'base capture' wasn't going to be a part of ToD.
I am not going to dig up the old discussions but feel free.
ToD is going to be mission based (whether scripted or truly dynamic who knows). The types of missions previously describe were things like escort, intercept, bomb, defend, recce etc...
Hopefully, it won't be just a 'tweaking' of main gameplay (i.e. capture the flag).
Most of you [us] are just guessing what ToD will be but there have been long posts and interviews where Pyro and HT explain it.
It will be a mission based arena with an rps flavor.
