Serious Sam is a fast paced first person shooter by Croteam, emphasizing intense action over tactics and strategy.

There is not a whole lot of support, but Icculus has done ports for both the first and second encounters. These ports require the original game cd.

There is a bug in the linux client for both versions that in some places can only be worked around with fly mode: open the console window by pressing ~ and then type "please fly" to activate it.
