Serious Sam HD: The First Encounter Speedrun in

Difficulty: Tourist
Single Segment
Time: 38:42 (In-game time, without cutscenes)

This is far from the best speedrun in the world, but it'll do. Credit goes almost entirely to Freezard, the previous record holder, for the route. The time saved over the previous single-segment run was mostly gained from updating the route with his new IL tricks.

One of the big tricks I left out of this route is geometry clipping, which would save a few minutes, but requires particularly low framerates, while another major trick requires high framerates. You also need the latter to use the former, and considering it isnt consistent either way, I left it out all together.
