Engine of Sin

Engine Of Sin is a first-person mech simulation game where you pilot a colossal war machine against world-ending Kaiju. Manage your reactor, reroute power between critical systems, salvage the ruins of Earth, and fire apocalypse-grade weapons in battles of epic scale.

Operate the Titanic Mech

Alone inside a towering war machine, you are the last surviving member of its crew. Learn to master every system and turn your metal coffin into the ultimate weapon.

Vent reactor overloads before they trigger a catastrophic meltdown. Redirect power between shields, weapons, and life support. Adjust movement stabilisers, route ammunition feeds, and keep failing systems running in the middle of fierce combat.

Battle the Kaiju

The monsters that ended the world are coming for you.

Each Kaiju is a unique nightmare, with distinct abilities, attack patterns, and weaknesses. Adapt your tactics, exploit vulnerabilities, and choose the right arsenal before it tears through your armor or shatters your mind.

Explore and Rearm

Between battles, you venture into the ruins of the scorched Earth, driven by an oath to uncover the weapon that could finally take revenge on the Kaiju.

Salvage what remains of the old world, forge specialized munitions, recover forgotten technology, and undertake perilous missions to prepare for the next battle.

Uncover the Secrets

Dare to unlock the sealed chambers of your war machine.

Descend into its metal entrails, uncover the fate of your crew, and confront the presence that lives within. Will you cling to your humanity, or merge with the Engine of Sin?
