Be Quick or Be Dead is the 38th level of Serious Sam 2.
The first one he must do is a speed run through a desert environment while under attack by enemies such as Kleers and Bull Soldiers. If he runs out of time, he dies. Checkpoints are scattered throughout the arena, which give Sam more time to complete the arena. Sam manages to reach the end of the first trial, and is then sent back to his prison cell for tomorrow's game.
There are no secrets in this level.
