SteamWorld Dig is an action-adventure puzzler with strong Metroidvanian influences set in the SteamWorld Universe. You’ll need to dig deep into the earth, gather resources to upgrade your tools and abilities, take on enemies, solve challenging puzzles and uncover the secrets to save a dying town.
No. Dig is a offline single player game. It will always be there.
Nightreign is designed for co-op. You better play it before the servers go offline.
