Reviews

If you want to relive the halcyon days of the FPS genre, a time when games strove to be unrealistic and challenging, you can’t get any better than DUSK. Here’s hoping for future episodes.

That really explains DUSK well. This is shooter perfection and something fans of the classics need to experience. Maybe it doesn’t redefine what is possible with video games, but it beats out basically every other shooter I’ve ever played. I know I’ll be replaying this for years to come and I look forward to seeing what fans are capable of with mod tools.
