Welcome to Singularity, a game with serious time shenanigans, horrible mutants with a taste for human flesh, and masses of Soviet soldiers out to kill you—both futuristic and classic brown-shirted ones from the past. The plot isn’t overly complicated, but it’s a bit of a mess when you start to think about it, especially if you are sensitive to media tackling time travel. However, being a Call of Duty style shooter, you don’t actually have to give that much of thought, since you are here to blast things to kingdom come—regardless of which timeline the enemy belongs to.
