Got it the other day : played it for a couple of hours. Not bad.
The aiming is a pain but it might just take some getting used to. Doesn't feel as elegant as Halo just yet.
Graphics range for pretty good to ok.
Sound seems quite good.
Flying seems like its got potential but it can be very very annoying too.
Only a couple of levels in: I've read it gets much better.
Will persevere for the time being.
Had Enclave and Hunter for week : took them both back : enclave was ok but its the usual been there done that type of thing and the combat was really unweildy. Hunter was just boring: hack hack hack hack run away...hack hack hack shoot shoot ...yawn.
