The game looks great, and the voice acting is well done. That's about it.
The AI is messed up, having a bunch of animation-tied actions that the enemy can easily break, but you cannot. Hardcore difficulty just added a bunch of enemies and 0 resources to "make it feel scary/desperate" but it doesn't even accomplish that, only making the game feel poorly designed.
Enemies are repetitive, the combat falls apart completely when fighting more than one enemy and there is no way of knowing when or if the enemy is close to death, only have to hit them more.
"Heavy attack" only knocks enemies back, doesn't do anything to actually damage the enemy more or anything of the sort.
Complete waste of time and I'm glad I didn't spend money buying this game. The Dead Space comparison only works in terms of the look, everything else is a blatantly poor comparison. Stay away.
