EYE is great, but I'll play the devil's advocate and criticize the combat loop. The guns are great and they sound great, the designs despite graphical limitations are good, everything is good enough but....
Streum never got basics of level design and enemy feedback right. I'd even say EYE has the best enemy lineup and "combat design encounter" (inasmuch as the term can be applied for Streum games) because Deathwing and Necromunda had terrible enemy lineups and the combat encounters were so haphazard and badly designed, even when pseudo-random or handcrafted, to be almost infuriating. They have developed shooters for more than a decade and Necromunda had terrible enemies with terrible balance and terrible encounters. EYE is a tad better because the game is so broken and the weapons so good you don't notice that you're fighting essentially barely-moving, barely-reacting puppets spawned in random positions.
How can a studio work with shooters for 15+ years and don't have a single clue about combat encounters is beyond me.
