Steam review snapshots
Being able to rewind time by holding down the ctrl key is a fantastic feature!There is, however, a quite good infinite/rogue-ish mode, which does provide a lot of replay value – but I do hope that…Quirky visuals – Creative weapon redesigns, plus grenades that seem to freeze, if not outright kill enemies – You can deflect…It's a very interesting mix that creates a very unique vibe.Why it fits
Check it if you want action filtered by single-player.
