XG Blast! Is a fresh new take on the arcade shooters of yesteryear. Tight controls and razor sharp action are tempered by a considerate learning curve and an interesting premise. Your titular superweapon is incredibly powerful; blasting through hordes of enemies and saving your sorry ass on several occasions. Basically it resembles a capable blend of Asteroids and Geomoetry Wars... which can't be a bad thing in our book.
Oh, and it's less than tree fiddy.
