MegaBots Inc. lit up the internet last July when it challenged Japanese rivals Suidobashi Heavy Industry to a giant robot duel. The team of US engineers and tinkerers promised that the fight would take place a year from the challenge, and although the deadline has come and gone, MegaBots wants fans to know it's still working hard to deliver the robot fight of a lifteime. To keep interest ticking over, the team is releasing a digital video series (announced last year) following them as they upgrade their bots, with a new teaser released today.

Speaking to The Verge, MegaBots' Gui Cavalcanti says the series will span roughly 10 episodes with the first to be released on September 28th. Each will be five to 10-minutes long, and will look at upgrades including a 350 horsepower caterpillar track base, a new roll cage, and melee weapons including a chainsaw and giant screw (the latter is reminiscent of the main melee weapon used by Bioshock's Big Daddy characters). "The series will focus on the science and engineering behind how to design a giant robot that's actually built for combat," says Cavalcanti. "Including testing new weapons, destructively testing the Mark II to see how it fails, studying human combat techniques, and more."

When it comes to the duel, though, MegaBots will still not say when or where it is taking place, explaining that this is due to various non-disclosure agreements signed with Suidobashi and other partners. Cavalcanti stresses that both teams are "100 percent committed" to staging the duel, though, and adds that while building the robots is comparatively easy, the hard part is arranging the contracts and getting giant robots "explicitly built for combat through international customs." Pity the poor TSA agent who has to deal with that.
