This is an amazing title. I was playing the demo for weeks last year, and it was equal parts elating and infuriating (in a good, rougelike-y way). Really happy to see it come to GOG. Can't wait to get stuck into the full game and see how it develops.
Just a fantastic game, through and through. The native linux build runs absolutely beautifully, good visuals, banging soundtrack, great level design. I'd say that Ion Fury is more frantic than the old Duke games. It's definitely a little more 'Brutal Doom' in that regard, although the AI is much more challenging. I've not seen a single frame drop during my play time. This is a very faithful homage to the FPS games I grew up playing in the 90s. I had high hopes for this game, and I have to say that it has met all of them. Really good fun. PS. I tried playing this with a controller at first and, while that's doable for the first 2 or 3 levels, a mouse and keyboard really is a necessity in my opinion. Way less fiddly, and a lot more head shots! So buy it. Buy it now.
