European development studio Croteam has already begun preliminary work on an Xbox version of its acclaimed first-person shooter Serious Sam. Currently, the company plans to release the Xbox game as a compilation of the original PC game Serious Sam and the upcoming sequel Serious Sam: Second Encounter. The Xbox game will combine many of the levels found in both the first and second game and will include all the enemies and characters from those games. Additional options, like the possibility of network support for the Xbox version, have not been discussed at this time.
The Serious Sam engine is already up and running on the Xbox. In fact, it is currently being used by 3000AD to develop its own Xbox game, titled Project ABC. Pending final negotiations with publisher Take-Two Interactive, Serious Sam for the Xbox could be released by year's end.
