Wow that's quite the list!
And Hero System!? That sounds like a lot of work!
I would create something simple from the ground up to really capture the quick and fun spirit, especially since you're so passionate about it.
In my head, I'm imagining the GM and the players frantically moving ships on a grid, pausing only momentarily to throw down a shot template. Maybe there's a clock that ticks up in one round increments that helps you keep track of weapon cool downs, enemy spawns, and when enemies fire. That would be intense.
Round 1: Start
Round 2: Orbs spawn A8,D8 (However you label the grid)
Round 6: Orbs activate [50% fire, 50% move]
Round 10: Great Beast (GB) spawns C4; Orbs activate [""]
Round 12: GB activates [80% Laser Breath, 20% shields]; Orbs despawn
Something like that. And the entire time the players are free to navigate, fire, or use powers.
Anyways, I would create your own thread about it. You wont get very many replies, but would be a neat place to share your ideas and progress.
