Courtesy of a previous 343i Competition that I entered, I have a Defiant Map Pack code to give away.
If you fancy your chances, then I’d like to test your artistic skill. Simply send in a picture/painting or screenshot of an EOD helmet.
The winner will recieve the aforementioned code and their work will feature in Volume 2 of Halo: Revolutions released later this year.
Second and third place will also see their hard work take pride of place alongside the winner in Volume 2.
All entries should be submitted to the following e-mail address:
thesecretswithin@hotmail.com
The closing date is midnight GMT June 3rd 2011.

Can I still enter for the artwork of an EOD helmet? I read on a different page that you changed the requirements.
I did change the criteria for the competition, so unfortunately I can only take screenshots. But I’d still love to see your work. Who knows, it might even get a mention.
