Serious Sam
This version of Serious Sam is based on Serious Sam: Gold, with several
notable differences. Like the Gold Edition, it features levels from both first
and second chapters; the weapons from the second part can be used when playing
the levels of the first one as well. The levels are generally somewhat smaller
than in the PC release.
The most significant change comes in the form of a life system. Scoring
100,000 points grants the protagonist an additional life, allowing him to
respawn at the same place after having been killed, rather than forcing the
player to return to the last checkpoint. Combo points are awarded for
executing specific attacks rapidly, contributing to the overall score. The
save system has been somewhat modified, with telephone booths representing
checkpoints.
