I actually like the name Project Landsword. How did you come up with it?
It's meant to sound sort of like an old 80s/90s future soldier program. There was Land Warrior and the Future Force Warrior program meant to test new infantry technology, and there were various military studies like Project Camelot. Britain also had a now replaced designation system for their military projects called the Rainbow Codes. Blue Steel for example was a nuclear standoff missile and Green Mace was an anti-aircraft gun.
So "Project Landsword" in this universe would most likely refer to the player mech's development program.
Giving the game a suitable localized name was one of my first thoughts actually. Literal translation of Landsword would sound a little silly in Russian, and the only relatively suitable name that came to my mind is "Проект "Меченосец"". If anyone else speaks Russian here, feel free to suggest your names.
