how can i make the reaver or carrier hold even more ammo? Also, i was thinking that if you can make infantry upgrades up to 255, can you make the marine range upgrade go higher than its first upgrade? or give the science vessel MORE power capacity?

carriers and reavers stock \/

...what?

armor and attack damage upgrades are the only upgrades that can exceed level 1.
Everything else is like either you have the upgrade, or not.

However don't forget scarab damage is also an attack damage upgrade and thus can exceed level 1.

You can make them be able to upgrade it multiple times by going to

Scenario>Tech Settings>Upgrade you want

Then change the maximum level, but it doesn't keep increasing it, it just costs money and does nothing the second time you buy it.

lol alright thanks again

Energy capacity? Nope, you won't be able to do that. You'll get the same result by making the abilities cheaper. For example lower the costs by 50% and it will be equall to a standard vessel having 400/500 nrg(depending on upg)
