Being a huge mecha fan, and having done plenty of LEGO mecha, I decided to share my newest (and in my opinion, best) series. The Frames come in three versions (so far). I don't have much of story or anything to go with them, but I do have plenty of weapons built for them, and I'll be working on Striker Pack style add-ons soon.
Here is the weapon selection. It's mostly down to things being energy based or projectile based, with two shields and a sword.
This is the only equipped Frame I've done so far, but I think it turned out well.
