Konami has started its own Code Hunt contest. The prizes include a Big Boss PSP bundle and $10,000. That’s worth it for the work, hm?

Japanese clothing retailer Uniqlo is also getting in on the Metal Gear Love with a line of limited edition t-shirts celebrating Peace Walker. The 10 designs come with codes that, when entered, will give you access to an in-game shirt that is the same one as you purchased as well as a new soldier.

The shirts will be available for sale both in Uniqlo stores and online on June 11, 2010. To celebrate, series creator Hideo Kojima will be at the global flagship Uniqlo store in New York City from noon to 2:00 p.m. on the day of the shirts’ release to sign autographs. That store will also be giving away several Metal Gear prizes.
