From the Steam sale:

Overlord complete pack (rarely on sale!)
Prototype (according to the interwebs this is the uncut, indexed version; hard to find in Germany for cheap)
5€ each.

Hitman 1 is off the index (after nn years the rights owner can request a new assessment by the BPjM; this one was successful). So sales for the first Hitman for Germany too should pop up everywhere around the new Hitman release.
