The Capcom release includes controller support and cloud saves.
GOG’s Dino Crisis release contains the original Capcom game with compatibility work for modern PCs. The store places it within its Preservation Program and lists support for Windows 10 and Windows 11. Primary source: official description and credits.
The product is single-player and includes controller support and cloud saves. GOG also identifies it as DRM-free, meaning that playing does not require an activation check or an ongoing internet connection. Primary source: official description and credits.
The game’s premise begins with a scientist reported dead in an accident during research into Third Energy. Information brought back from a secret military project creates a reason to investigate that earlier account. Primary source: official description and credits.
That scientific mystery belongs to the existing game. The GOG edition’s documented purpose is to keep that game usable on current systems, with the original content retained rather than a new storyline replacing it. Primary source: official description and credits.
