Shoot for a "Love, Death & Robots" anthology that hits all the separate points listed here. See what sticks, see what fails and if there is an audience that wants more go with what worked and build a series from there.
- Solaris Gladiator short to open, easy concept to get "Robot Gladiator fights? I'm on board!"
- Infantry squad vs a lone 'Mech, introduce two factions at war and how scary the BattleMech is vs conventional units
- Some "last stand" type thing with merchant guards vs pirates off in the periphery, show how interstellar travel is a thing and how far humanity has fallen
- "Grand Battle" of proper house units clashing and the protagonist's squad need to "do the thing" to turn the tide
