Did the final mission last night. I'll reserve opinion on the ending for now.
hmm, yeah, not entirely convinced by the ending. maybe its different on different difficulties - if you finish on ironman impossible you get a happier one, perhaps?
not entirely sure of the point either - the ethereals orchestrated the whole thing to encourage us to awaken our psionic power so that we would ascend (and presumably, help them to?)? in which case, why did they still try and kill us once we'd got our power?
i did like when the other 2 soldiers stopped at the door to wait for the volunteer, and she just threw them through instead
glad i gave her the killing blow (a mindfray on an ethereal commander, no less!) though, good final shot for her, i think
