The Room 4: Old Sins review

The Room 4: Old Sins is the pick for solo players who want more space than the first The Room offers. Fireproof Games builds this fourth entry around a strange, multi-room dollhouse found in the attic of an engineer and his high-society wife, who have disappeared while hunting for a precious artefact. You explore unsettling locations, follow obscure clues and work bizarre contraptions to uncover what happened inside Waldegrave Manor, so it feels closer to moving through a set of escape rooms than opening one safe. The studio says it rebuilt, re-textured and re-lit every object and environment for the PC release, a clear upgrade over the mobile version. It costs $8.99 on Steam and needs a Windows PC with 4 GB of RAM and 10 GB of storage. Like the rest of the series it is single-player only, and it makes the most sense after playing the first game, which costs $4.99. We compared documented features and published prices.
