German company Crytek has filed a lawsuit against Cloud Imperium Games and Roberts Space Industries, the developers behind Chris Roberts’ ever-growing and still-in-development MMO Star Citizen.

The lawsuit was discovered via the California Central District Court, where Crytek alleges that CIG has infringed on their copyrights by using CryEngine to develop non-Star Citizen game assets, like the stuff found in Squadron 42, their single-player game set in the same universe as the MMO.

“Crytek has not been compensated for Defendants’ unlicensed use of Crytek technology in the Squadron 42 game, and has been substantially harmed by being deprived of that compensation, which would ordinarily include a substantial up-front payment as well as a substantial royalty on game sales,” Crytek argues.

Crytek is also accusing CIG of deleting Crytek logos in marketing materials and splash screens from around the same time period that studio boss Chris Roberts (pictured above) started calling their engine Star Engine and not CryEngine, which is also allegedly a breach of the original licensing agreement.

Furthermore, Crytek is demanding “all direct damages (estimated to be in excess of $75,000), indirect damages, consequential damages (including lost profits), special damages, costs, fees, and expenses incurred by reason of Defendants’ breach of contract and copyright infringement”, as well as a cut of the profit, punitive damages, and a permanent injunction against CIG using CryEngine.
