Would people like to see vehicle upgrades, and if so, what kinds of upgrades should there be? Some thoughts:
-Ablative armour.
-Supercharged engine
-Increased fuel capacity
-Nitro boosters (he he he)
-Increased ammo capacity (or any listed ammo capacity, for that matter)
-Extra comfy seats
-Extra shiny gilded exterior
-Upgraded fire suppression systems
-Sensorium array
I realise most of these might be reflected by adding vehicle traits, but it would be nice to see some rules on how an enginseer, or a tinkering guardsman might accomplish these. Additionally, vehicle 'downgrades' could be made use of.
As an extra note, what about weapon upgrades that could be added to vehicle weapons. Some of the existing ones could be appropriate, although perhaps not a melee attachment.
Despite how awesome a battle cannon with a bayonet might be.
