Probably the world's first 100% walkthrough of the Serious Sam: The First Encounter. The goal is simple: kill all enemies and find all secrets. The problem is that a lot of enemy spawners are broken, so some of them cannot spawn enemies and some of them shall spawn enemies after 27.(7) hours. Wow... I decided to kill as much enemies as you can for every level, so it's more like Max% instead of 100%, but I'm calling it 100% because it's fancier and clearer.

Notes:

1. A huge thanks to @decino for his 100% walkthrough and broken kill counts research, this is actually what inspired me to do such crazy run.
2. Thanks to @Kaelthas for discovering a way to go out of bounds on any level. This is the revolutionary glitch for the Serious Sam: TFE speedrunning, but it also made the 100% possible. Killing marsh-hoppers at the template room on Sacred Yards level is possible now, so instead of 358 kills the maximum number is 374. This is the unique walkthrough for sure, so this is why I am calling that run the wolrd's first 100%.
3. On Dunes level there are two bio-mechanoid minor spawners, delayed by 100 000 seconds (27.(7) hours). So I had to wait 27.(7) hours in order to achieve 100% on Dunes level.
