Is this really an FPS? I know there's 3rd person FPS games but this feels more like it uses auto-targeting. Or semi-auto anyhow. If not, the game really needs a targeting reticle.
And if anything, this reminds me more of Bioshock than CoH. Though Bioshock could probably be traced back to the Jedi Knight games. You get conventional weapons as your main attacks, but with powers that you could use as wildcards without even putting the gun away. In Jedi it was all very force-centric, but Bioshock's powers were pretty interesting. Fire, ice, lightning, psycho-kinetics (pull an object to you and then throw it at someone - pretty sure you could catch bullets in a mind vortex and throw them back too), insect swarms, wind, illusions, hypnosis, hacking...
Btw, that mentalist demo... I don't think you actually 'confuse' the targets and watch the fur fly. I think you actually invade their minds and temporarily take control of their bodies, from their perspective. That's pretty darned cool.
