I have only completed 5 chapters in the single-player campaign and so far I reckon the story is quite interesting. I guess it should not be a surprise since the developers got Gav Thorpe to work the plot.
The best way to introduce the story is to watch the introduction video.
The sounds are awesome. The guns sound powerful. Whacking with your fist or sword gives a very satisfying contact sound, even when hitting walls or railings. The ambient sounds and that of the Genestealers also sound awesome.
Although the Space Marines do not speak much, what little speech the game has, does sound very good.
The graphics are Warhammer 40,000 wonderful. Your fellow battle-brothers, the enemies, the space hulk interior, the details on weapons, the exploding sparks from your Power Fist when you pound a Genestealer into oblivion – everything in the game looks awesome.
Many aspects of the game’s difficulty can be adjusted. There is the usual how much damage the enemy does or how much health they have. Then there are the helpers with options like enabling auto-mapping before you find the magic map or whether you want auto pause at certain times. I cannot remember another game with this many options for tweaking the difficulty level.
The puzzles in The Fall of The Dungeon Guardians are quite clever. There is no hand-holding or even hints as to what to do. Eagle eye observation is also required for some puzzles. Many times I have passed an area and did not notice that key thing that was required for a puzzle.
In general, I hate puzzles, but I was quite impressed with how they were presented in the game. Most likely I will get stuck and start reading walkthroughs though.
The controls are very easy to use and the whole game can be controlled entirely with the mouse alone. For people like me, there are plenty of shortcut keys and they are fully customisable as well.
The music sounds nice. Unfortunately, there are only a handful of tracks so it does keep repeating. The good thing is, it does not grow annoying with time.
The graphics look very nice. It is not the best, but it still looks very nice. The animations are fluid. The lighting gives a nice dynamic effect to monsters as well as the surroundings. Objects and the environment look well detailed, although the number objects seem a bit sparse.
