The HD version is good, only area that left disappointment was some basic textures that could have been given more depth.

Dusk was after my first playthrugh one of the best shooters I have played. And while it still is great, my enjoyment of it has infect dropped a little. Nowadays, I am especially drained by the lack of geuninely interesting enemies and perhaps to an extent level gameplay wise? I'm unsure about that last complaint because at the same time Dusk's biggest strength are some of its standout levels and their atmosphere. Episode 2 and especially Episode 3 constantly reward you with breathtaking absurd sceneries.
The soundtrack, of course, is also good and the base gameplay is cool aswell. It's just that it does not hold up on replays.
