Alpha Prime (2007) (PC) (Black Element Software)
Alpha Prime - not to be confused with Alpha Protocol or Alpha Centauri, by the way - couldn't exactly be called a particularly good game. Big deal; I got it for less than 1,5€ (as one of the many games I've bought during Steam's ongoing "Perils of Summer" sale), and playing this game is certainly a more worthwile experience than, say, eating a really cheap sandwhich...which is just about the only thing you could otherwise do for 1,5€.
I'm a sucker for simple arcade shooters, and this decidedly non-AAA title delivers functional run'n gun stupidity (within a surprisingly capable internally developed engine) despite dreadfully generic environments and one of the most laughably bad scripts in recent gaming history. Recommended for genre fans only, as they say...
