It has been unavailable for 10 years but R.U.S.E. from Eugen Systems has returned, with upgrades and full Steam Deck support too. Direct support from the developer for the Steam Deck, plus Valve rated it Steam Deck Verified.
The new Definitive Edition rips away Ubisoft as publisher with Eugen Systems now having the full rights to it. Nice to see for a classic strategy game that's the predecessor to the likes of the Wargame series, Steel Division, and WARNO.
From the announcement:
Originally sidelined due to distribution constraints, this pillar of the RTS genre is returning to the spotlight, now available once again for both veteran commanders and a new generation of players.To mark this relaunch, the game has undergone a series of updates to ensure seamless performance on the newest hardware specs. We are also proud to confirm that R.U.S.E. is now fully compatible with Steam Deck, allowing players to master the art of deception on the go. Finally, the game now includes all the DLCs ever released for free.
Existing Owners: Players who previously purchased the game on Steam before it was delisted will keep their full access to the title, including all new technical updates, and all DLCs at no additional cost.
“We are incredibly excited to bring R.U.S.E. back to its rightful place,” says Eugen Systems. “Our goal is to allow a new generation of strategists to experience a title that defined an era and paved the way for our later successes. The battlefield is open once more.”
