I heard Armored Core 4 is the best of the main series - or maybe it's For Answer IDK - and I've had it on my shelf for a while now. Gave it a spin this evening and it seems pretty amazing, especially the soundtrack. You can really tell it's from the Demon Souls era.
Got a weird question though: Can you not fly by default in AC4? In AC1 you could fly by default. Don't remember AC6 at the beginning. Been pressing all kinds of button combinations trying to fly, and instead I'm just dashing/boosting forward. Maybe the starting AC configuration doesn't have flight yet?
I ask because I also tried to play Terminator Salvation earlier while I had the PS3 plugged in, and some buttons didn't seem to work at all in that game, so not sure if the PS3 is bugging out or what.
If AC4 is a game where you have to build up to flight via upgrades, then cool, but just making sure it isn't some sort of glitch. I checked the control layout and there's nothing about flying, just "Boost" (which again only makes me boost forward, not straight up like it would in AC1).
