🎮 Play Chaos Engine, The Online (DOS)

The Chaos Engine is a 1993 top-down action shooter developed by The Bitmap Brothers for DOS. Set in a steampunk Victorian era, you choose two mercenaries from a roster of six—each with unique weapons and attributes—to battle through four worlds mutated by the titular machine. It stands out for its cooperative gameplay, pairing you with either a second local player or an AI companion.

How to play

The goal is to explore each level, activate the nodes required to unlock the exit, and survive hordes of mutated enemies. Money collected along the way is used between worlds to upgrade your characters' weapons, health, and special abilities.

Tips

Focus on upgrading your primary weapon first, as enemies absorb significantly more damage in later worlds. When playing solo, keep an eye on your AI companion's health and let them grab health pickups when they are low, since you share a pool of lives.
