Microsoft is holding their first ever Xbox Live Arcade sale this Sunday and Monday. That's right, the manager is out of town and the workers have discounted stock to crrrrrazy low prices. You'll be able to pick up these four games at half price:

Small Arms - 400 Microsoft Points (normally 800 Microsoft Points) Easy to pick up but hard to put down, "Small Arms" is a frantic multiplayer action game with the feel of an arcade shooter.

Zuma Deluxe- 400 Microsoft Points (normally 800 Microsoft Points)
Explore more than 20 realms in Adventure mode and put your skills to the test in this fast-paced puzzle game.

Gauntlet - 200 Microsoft Points (normally 400 Microsoft Points)
The original dungeon crawler lets four adventurers explore and fight together as a warrior, valkyrie, wizard, and elf.

Dig Dug - 200 Microsoft Points (normally 400 Microsoft Points)
Experience the fast-paced action of this quarter-cruncher from 1982 as you take control of Dig Dug himself and vanquish Pookas and Fygars.

An odd selection of titles but I'm glad to see that Microsoft is experimenting with dropping the price on older Live Arcade games.
