Serious Sam: The First Encounter is a classic first-person shooter game developed by Croatian game studio Croteam and published by Devolver Digital. The game was released in 2001 and gained a large following due to its intense gameplay, challenging difficulty, and humoristic approach.

Players take on the role of a hero named Sam "Serious" Stone, who must fight his way through hordes of creatures from ancient Egyptian mythology, including giant scorpions, gnaar (bipedal rhinoceros-like creatures), and headless kamikazes. Along the way, players can collect different weapons and power-ups that help them defeat the waves of enemies that come at them.

The game features 15 levels, each with their unique setting and monsters to battle. From ancient ruins to desolate deserts, players must traverse different environments and fight their way to the end of each level. To add to the challenge, the game also features some challenging boss battles that require players to use all their skills and weapons to defeat.

Serious Sam: The First Encounter was praised for its fast-paced gameplay and impressive graphics, which were ahead of its time. The game has also spawned several sequels and spin-offs over the years, cementing its place as one of the best first-person shooters ever made.
