Apex Games is putting out the word on Demon Core, a survival-oriented first-person shooter they are looking to release for Windows and OS X by the end of next year. The game is currently the subject of a Steam Greenlight campaign where they offer this gameplay trailer showing off environments and this gameplay trailer which is considerably shootier, and they plan an Indiegogo campaign to help the Finnish developers finish the game. Here's an outline:

Demon Core is situated in a Russian research laboratory, working on solutions for potent sources of energy. The female protagonist of the game, a scientist working in the said laboratory, is faced with a dire situation and is forced to use all possible means she has to survive the overwhelming attack set upon the lab. The innovative gameplay elements allow the player to blend in among the other victims, even feign death over other who have already fallen in the battle. Players will be given tools to set up traps, sneak around enemies and start working on them from the top of the chain; the enemy squads follow a chain of command, which allow the player to target a commanding officer or a radio operator, sending the squad into disarray and cutting off any calls for back-up.
