@Mr_NutterButter Even back when their first game, Alien Shooter, came out back in 2003, isometric games were being phased out as even budget PCs were starting to come with dedicated GPUs. They are a small team in Russia though, and they even said in an interview that they felt like they weren't ready for fully 3D gaming at the time. But even almost 20 years later, they still insist on making prerendered isometric games, despite tons of 3D engines being available now.
Maybe, they just like the style. I mean, it does have it's charm. I kind of like it. It reminds me of when 2D games weren't going to fly, so if you can't do 3D, then you had to at least fake it, and an isometric perspective with pre-rendered sprites seemed to be the easiest and most effective approach.
