Silence of the Warp: OoC
So I was thinking about Wargear:
Without resorting to spoilers, you will be isolated from the Imperium at large. There will still be opportunities to gain resources, but a lot of it will be based on finding them or bargaining for them.
So, instead of Requisitioning resources like the Deathwatch do, what do we think about a more traditional inventory system? The Company has weapons and wargear to choose from, and you can select them for your missions. Gradually you can expand your inventory with rewards and reclaimed items. You may also gain the ability to supply yourselves with munitions like ammunition, so a certain amount is available at the beginning of missions.
