Chex Quest (Doom total conversion mod for The Ultimate Doom)

Chex Quest was released in 1996. It is a total conversion Doom mod. It contains five levels, but then continues on with the regular Doom levels after that. Here I play the five levels, including:

E1M1: Landing Zone
E1M2: Storage Facility
E1M3: Laboratory
E1M4: Arboretum
E1M5: Caverns of Bazoik

This is quoted directly from Wikipedia:

"Chex Quest is a non-violent first-person shooter video game created in 1996 by Digital Café, originally intended as a Chex cereal promotion aimed at children aged 6–9 and up."
