Scarabaeus

Scarabæus is a 3D adventure game made by Andromeda in 1985. It is also known as "Invaders of the Lost Tomb" in North America.

The game starts with the player landing his spaceship near an Egyptian tomb. He wears a spacesuit and is followed by a dog. His aim is to collect the ancient treasure of Scarabæus, a smaragd in the shape of a dung beetle kept inside the tomb.

Although it's not shown in the presentation, the explorer gets bitten by a spider upon entering the temple. The tomb contains several vials with an antidote, and several others with poison, and the explorer must solve some puzzles that will reveal which ones he can drink and which ones he must avoid.
