amok: Larva Mortus is unlocked, it is Steam only.
Net bonus is
Greed: Black Border. This is an SciFi hack'n'slash, and it is better executed than Chosen, I think. It is not a bad game at all. It has been in several bundles before, and I guess that if the trend continues, it will be Steam only. I do not think it is sold DRM free anywhere, it is Steam or Securom.
edit - darn ninjas... grumble...
edit 2 - The bonuses so far are quite good, could almost argue that they are the best games in this bundle. It is a shame I already got them all
Thankfully I have a friend who is just getting into PC gaming and has rather taken to the "easy play" of Steam, so I guess I will just continue filling his games with the extras then. Already bought 3 games in this pack with the sole intention of gifting them over, and two HB's
On the other hand rather limited for people like myself who prefer DRM free gaming..
