For a long time, it was believed that any game adaptation of film material was going to be bad. There were a few exclusions, but overall, it seemed they were cheap moneymakers. More recently, we've seen adaptations viewed as worthwhile games. This may or may not be the case for R.I.P.D.: The Game.
Having never heard of a film by this name until seeing a billboard today, there's little I can offer as info other than the basics. Apparently the film is a supernatural action-adventure tale featuring two gunslingers. The game appears to offer this core bit as well, although likely focuses on far more shooting than the film will.
The game itself is a third person arena-style shooter and appears to pit you against a lot of humanoid creatures. There is a single player mode as well as co-op. Atlus also happened to publish it but then again they have published weirder. You can pick up R.I.P.D.: The Game for $9.99 and, no, it is not a part of the Steam sale.
