Wolfenstein 2009 has been completed and I shall never play it again. I swear people only want this game simply because they cannot buy it. Return is a classic, I'd argue The New Order is a classic as well but Wolf 09 is, at best, wholly average. There are some interesting ideas in Wolf 09 in the Thule Medallion, the Veil, Veil powers and sci-fi weapons that are mired by regenerating health (this changes the pace of combat so much), how abuse-able the Veil powers are, terrible AI, unsatisfying combat that feels too slow, and terrible, cramped level design.
You get some fun fantastic weapons to play around with but for the first half of the game the ammunition is limited to the more pedestrian weaponry. You can see why because the sci-fi weapons are all over powered but then that leaves you with just three normal weapons for the first half of the game because there are so many weird omissions--no pistols, no grenade launchers, no shotguns, no sniper rifle (unless you upgrade the k98 to being one). The Veil powers while fun aren't integrated into the gameplay often. I found it easiest to simply abuse the slow time veil power once I got the AoE on activation. It was so easy to nuke large groups of enemies and quickly clean up the remaining few. Usually hide around a corner, find some veil energy fount and camp while both my health and veil power meter filled, popped out, do the same thing all over again. Fully upgraded Empower was better late game though.
Wolf '09 could have been something with a bit more love and polish, maybe I'd be more forgiving if I played it when it originally came out but man, it's kind of shit now.
