The Combine Strider and Gunship synths from Half-Life 2.My original versions of these can be found on MOCPages here: [link] I've since improved them a bit to make them more accurate.As I explain on MOCPages, the Strider wasn't originally my design, I saw someone else's LEGO Strider on MOCPages and thought that it looked the best of any I've seen (that was closer to minifig scale). So I made mine based of that one, but I didn't copy it completely, of course. But since then, I've made my version even better: I gave it more accurate colors where I could, and I even made the pulse gun on its "head" able to swivel and look around like in the actual game.I don't really have anything special to say about the Gunship.Also, Gordon Freeman with his RPG.
