Download Chex Quest
Chex Quest is a great game, even if it is designed in DOS and it will seem antique to you. The game dates back from 1996 but surprisingly enough, it has three dimensional graphics and a gameplay that is similar to Doom. Like in this classic, you will find the HUD in the lower area of the screen.
The planet of Barzoik is slowly being conquered by aliens made up of green slime and you will have to stop them. Throughout the five levels that are available you will encounter more powerful monsters but also different weapons that become better and better.
