One can't praise the Graphics Team high enough. Whoever was orchestrating that, either in a lead role or by providing just the right assets, must have either been a die hard 40k Fan, or have gotten an excellent understanding of the 40K Universe and especially the grim behemoths, that Space Hulks are supposed to be. The abysmal and vast wreckages of those ill-fated Space Ships Graveyards, aimlessly drifting the Warp and then popping up once in a while in humanity's reality, are excellently crafted and with insane, loving detail. Futuristic, industrial designs are stitched together with medieval Cathedra halls, blending over in just the right way to make it look like something that has been moulded into form, but where the components are yet opposing. The Terminator Suits are designed to point and with awesome details like the "The Emperor protects you" lettering, when peering down hard enough. You actually feel heavy and somewhat protected in those thing, but don't worry, this will go away, once the Tyranids start pouring in. Aaaaand those were the good things of the Game. I actually am grateful that they give you full 10 Minutes to enjoy all of the above, before the action starts, so you can let it sink and again, praise the girls and guys who made this so fantastic. The story never picks up the bleak and sombre tones it sets in the intro again (but hey, this is a FPS in the end.), Sound design is horrible and bland. Where Vermintide 2 uses dramatic Scores when things get nasty to upscale the tension, SH just uses nothing. Weapons sound more or less the same, be it a Bolter or a bigger gun and of course you still encounter the occasional glitch, where one of your fellow marines is stuck into a wall and then you need to restart the whole thing from scratch. Something that is super awesome if you just spent an hour playing a level. Buy it for the visuals and while it's on sale.
These two parts of the series have everything the earlier parts already had: Not quite ordinary Races and Classes to choose, turn-based and challenging combat with interesting spells and a basic attack technique model, as well as a huge dungeons to explorer. Beyond that you get a huge world to explore, a compelling and interesting storyline with tons of side quests, races gathering in factions (whose allegiance towards your party depends on your actions) and... Well, what else could you want? I spent the whole winters of 1990 and 1992 in these two games and so should you. There was nothing similarly worthwhile in the years between this and Baldur's Gate.
