Had the idea of rods that would detonate upon contact with any surface, somewhat alike the ones in crossout.
Upon use it'd do high damage to the resipiant but would have a high chance of disableing(or at least severely damaging) the user. I'd imagine that the explosive rod would reward good build design for the wepon's aplication!
Also thought about some sort of bomb dropper that would require the user to manualy detonate the bombs that the dropper would drop.
I'd think that this would require the user to have to have some skill to get good use out of the bombs!
Here's two playstiles I think could come from this:
Either set deadly traps as a ground unit or roleplay as a Douglas SBD Dauntless and blow people to smitherines with an agressive track and destroy playstyle
Methinks that would be quite fun! :D
