Microsoft will release Halo motion comic The Mona Lisa through Waypoint and the internet next Saturday, 23rd April.
It retells a story from the Halo Evolution anthology, set shortly after the events of Xbox launch title Halo: Combat Evolved.
"Sent on a highly-classified mission in the debris field of the Halo artefact, the crew of the UNSC Red Horse discover a derelict prison ship – the Mona Lisa – adrift in space," reads the official blurb.
"When a contingent of marines board this vessel, they come face to face with a more terrifying threat than the Covenant and are forced to battle for their very survival."
Ahead of the launch of the motion comic, Microsoft will this Friday make a number of changes to improve Xbox Live Halo portal Waypoint.
Your Halo: Reach service record will be fully accessible from Waypoint, so you'll be able to check your weapon stats and Challenges from within the Xbox 360 application.
The new Compare with Friends feature lets you compare your stats with your friends. Two new Waypoint career levels are added, as is the ability to launch the Games on Demand version of Halo: Reach – Bungie's final Halo game – from within Waypoint itself.
The Zune tech that powers "instant on" streaming ports over, which should make watching videos within Waypoint faster and easier.
Meanwhile, a number of Halo Avatar items launch tomorrow, 14th April, including Spartan helmets and Red vs. Blue t-shirts.There's even a Flood infection form for your Avatar.
Halo is 10 years old this year. Speculation is mounting that Microsoft plans to launch a high definition remake of the first game in the series, Halo: Combat Evolved, in November.
