SuaSide from NMA, one of the intrepid ninjas that saw the Fallout 3 demo and lived to tell what they saw, dropped by this blog and answered a very long set of questions made by Gimli about VATS, melee and combat in general:
Pete queued up to 3 aimed shots in my demo. I believe the last actions weren’t necessary though, since if i recall correctly the target was dead by that time. However, it is possible to queue a lot of stuff, but I haven’t seen how that plays out if they are all needed. (it also should be noted that Pete queued a reload in VATS while Todd said only aimed shots are taken in VATS. this could be interpreted in many ways, i guess.)
We’ve seen no melee combat at all, so we can’t answer anything about that. I dont believe Pete knew the answer to our melee questions. I don’t think it has been implemented yet in any other way than how Oblivion used to work. So they’ll need to adapt it to VATS before answering any questions about it.
Thanks for your time SuaSide.
