Warhammer 40K: Mechanicus is unique tactics game and for many people is also one of the best WH40K game but not for me...
Mechanicus story is probably best part of the game, where it's up to you to decide which mission needs more attention than others, I've chosen word "more attention" because game at the start adds timer and if it fills, campaign will cut shortly to boss fight and if you are not prepared it will probably end not so well for you - it's very reasonable choice to make campaign like this so that you can't grind and you need to plan your every move. There are few endings, each one is different and they are accessible through your actions and missions you take.
Like I said higher, gameplay is unique, what I mean is that there is no cover system and power of your units is based not as much on tactics than it is based on augmentations you choose for your tech-priests. Augmentations gives you armor and weapons, there are many combinations you can do with them and each one is special these augments augments change also how your tech-priest looks which makes this game even more fun.
Through campaign player will cross segments with decisions to make where you choose one of three different options, this thing adds interesting lore diversity. As for the flaws Mechanicus on "Normal" difficulty is difficult at the beggining and it's going to be boring in mid to end-game which left me dissapointed with boss fights that turned out to be too easy just also I should say about level layouts that after some time are getting repetetive, animations are cute but too long (and you can't skip them) - like I said; these gameplay flaws in time make this game dull.
Graphics are rather stylish than realistic, effects are very cute and pleasing to the eye. Each weapon have it's unique effect and sound, music is fantastic and voice acting gives you creeps.

Summary:
Game is pretty fun but it's going to be boring in time so don't play at "Normal" difficulty, take higher ones.
7/10 - worth money and yours attention especially when you love WH40K universe.
