MoonMaster: RahKon is the latest from Lost Vectors, creator of BowMaster Prelude. Gone is the resource management and medieval setting, but in its place you'll find a space-themed setting along with a similar physics engine under the hood. You play the role of a ball on the moon shooting rocks and a UFO with your lasers. The goal? Try not to get smashed to pieces.

As a casual gamer, you have certainly come across titles that fall into the defend-your-castle category. BowMaster Prelude fits that description as well, but certain aspects elevate it above other candidates, such as earning experience points and gold to recruit an army, the ability to upgrade and buy different arrows, and a unique feature that lets the hero leave the castle.

Akai Ryu, or Red Dragon, is a surprisingly addictive little shooter created by Jason Reinsvold and available to play on his LostVectors website. The object of the game is to stay alive as long as possible while shooting down all of the various enemies that come into play.
