Cleared the campaign on normal in about 22 hours with most of the secondary objectives, the game is very similar to red solstice 2 with focus on stealth.

Positives:
The gameplay is fun. lots of exploration, tense moments, and tactical options.

Negatives:
The progression system for the marines and your ship(base) is a bit bland, lots of small number upgrades. Few of the missions/maps are not well made / fun, ex: the mission that clearly draws inspiration from alien isolation and the one on a hostile ship filled with small rooms and enemy patrols everywhere.
The story is meh, especially towards the end.
Not able to position individual marines makes it hard to utilize/line up certain weapon skills such as sniper/rpg
Alien patrols sometimes just instant respawns as soon as you kill them in stealth.
Game introduces a doomsday timer pretty early on even though the timer is pretty generous, so some people might hate this mechanic.
Going guns blazing can be very punishing since alerting an alien will always cause a wave of alien spawns and increase future spawns.

only ran into one bug the entire play-through where one of my marines spawns inside a shelf and couldn't get out after loading a save, had to load a earlier different save to resolve the issue.
