LGM stands for “Little Green Menace”, you can even see a little green alien dude in a cockpit above the trigger. The blogpost also mentions how they’re “partly autonomous” and will circle targets to shoot lasers at them before attempting to return to the dock to replenish ammo
It’s like your own little portable squadron of ufos, this thing is so so creative and fun looking, I’m so excited to use it, and for what kind of WWs await us in these later seasons!
