Poor and unpolished; certainly does not serve SST justice.
Of course all of us SST fans like would love to see the franchise turned fps, but this game (as far as the demo is concerned) serves SST no justice. Sure, the novelty of it will get fans and some fps fans riled, so did I, but after playing the demo, I must say that the developer needs to polish the game up quite a bit. The sound is barely passable, the graphics seem horribly outdated (though understandable after seeing all those arachnids), the controls are just ick, and the story seems wholly derivative of the movie plot.
This is a great idea, and I'm thankful for a developer finally producing an fps of SST, but from what I've seen so far... it needs a lot of work.
