Philip Muwanga’s Hexy Trench is the work of one man and is a great little multiplayer XNA Community Games experience at an affordable price. Up to 4 players build trenches connecting outposts to their main headquarters, then mount offensive and defense structures on top to battle each other, destroy all the other HQs and come out victorious!

It's highly simple and full of action as each player speeds around trying to get one up on their friends/acquaintances. There's also a single player campaign against bots and Xbox Live support for playing online. Hurrah!

You can buy it now for the Xbox 360 via the Xbox Live Marketplace for a measly 200 MS Points. Alternatively, try the demo to see if it's for you.
