Last year, I went to Toy Fair and saw some Halo Mega Bloks. They were pretty cool. This year's are better. This line, which I shot at Toy Fair 2011, is slated for release throughout the year.
(In case you weren't familiar with the brand, Mega Bloks are like Legos. I'm sure they get that allll the time.)
The Mega Bloks people also will have some releases tied to the 10th anniversary of Halo: Combat Evolved this fall.
