I've finished it after 35 hours on Hard difficulty. I had to clear the final level and that was it.
The game doesn't have a real pay-off. You don't get any clarifications about the main plot device - Maelstrom - or the companions or any kind of closure about anything. Most of the final "choices" are just cosmetic shit.
I'm somewhat speechless because I don't know how the devs can justify this mess: either they cannot write a proper story, the game is unfinished or they are planning for a sequel.
In any case I cannot recommend the game: the overall experience is dull and pointless without a real pay-off.
I cannot recommend it not even as the first game from a promising dev:
- the anomalies are reduced to pointless gimmicks instead of something more interesting,
- level scaling is retarded considering that your damage potential has a cap (no QA!?),
- there is no tactical level for combat (just spam disabling and aoe attacks) - no cover or flanking,
- generated-loot is simply No-No (one of the last containers in the game had 12 onions inside !?),
- at lvl 32 I had like 6 maximized skill trees but with the right perks someone could maximize almost all skill trees (real lvl cap is higher),
- redundant systems like fatigue, hunger/thirst which add nothing to the experience,
- cannot level up companions (!?) although you can upgrade their weapons,
- the writing is bad and the overall story is just a wasted opportunity,
- companions have a tendency to disappear after certain story events,
- the overall experience is a bait-and-switch (early EA part was "polished" but then the rest of the game is just thrown together)
- everything is just mediocre at best.
Whoever "designed" this game doesn't have the chops to create a good game. Probably Atom is better than this.
