The popular video game Titanfall (and its sequel) is one of those perfect universes that can translate into Lego extremely well. The first-person shooter stars some amazing robots that just ooze style. Marius Herrmann has created a small series of Titanfall Lego MOC’s. The creator worked hard to get some of the details as accurate as possible. Focusing on proportions, and color. The collection of mechs include Ion, Northstar, Ronin, and Stryder. Stryder is the only one based off the first game, and is actually and update to an older Lego MOC (the legs got completely redesigned).
Make sure to check out these Lego Titanfall MOCs over on Flickr, where you can find the original Stryder design and other Robots by Marius Herrmann: https://www.flickr.com/photos/velocites/30060726203/
