Is EYE worth it for the singleplayer alone? My internet connection pretty much eliminates the possibility of multiplayer.
I never tried competitive play, and only co-oped a little with friends. The single player is where it's at, and for me it was one of the more enjoyable solo FPS experiences.
It's a very weird game. I haven't tried the patch but the game seemed offense-heavy, in that it's easy to kill enemies and easy to be killed (though as a space templar you *usually* stand back up after a few seconds). I was impressed with the stealth and hacking mechanics, which let you detect enemies through walls and avoid them, or have them fight each other a bit. Those aspects can be ignored though if you choose strong weapons and armor.
It has a generously paced RPG upgrade progression which lets you invest in stealthy tech powers, twisted psychic powers, or overpowered weapons. About halfway through the first playthrough I got my money and strength up high enough for this weird pistol that kills most things dead. It sounds like a sniper rifle to fire. I dual-wielded it with a sword and felt like a space marine. This was all despite spending most of my money and points on stealth/tech stuff... You aren't locked into a certain playstyle, despite what the character creation would suggest.
It takes a while to get through the story mode, particularly if you do the repeatable side-missions for extra money (My favorite was raiding a warrior-monk temple to assassinate the leader). I enjoyed it enough to play through about 5 more times, eventually achieving the other 2 endings and unlocking the true secret ultimate ending, which made even less sense than the rest but was still oddly satisfying.
Good points:
Hack people through walls
Dual swords which block bullets
Several story high demons
Plot has moments of clarity
Bad points:
Lots of walking until speed upgrades
Easy to die a lot at first
Hunting for objectives in certain side missions
Enemy airships in a certain level, unless you have aforementioned pistol
Where am I, what's happening, why are they shooting me, why aren't *they* shooting me, did my ally just insult me or say hello
