I was just thinking, you know how in some games if you max something out, you get some sort of skill? I was wondering, could we implement those in the game? After 100% completion of said tree, not just in the shortest line to it I'lll throw what I thought of
Bow tree: undeflectable arrows. Can't be deflected by mk3 robots. I originally considered homing arrows, but those would be way too OP
Kick: Dunno, stronger kicks? If you kick them in the wall they die? Kick them and they lose a leg, probably?
Jetpack: ooh ooh jetpack can fly upwards, pretty useful for escaping and spidertron sniping
Unbalance: you don't just unbalance enemies, you throw their weapons away from them and they rush towards it to grab it first
Energy: Every enemy killed in a map regenerates a unit, or something less OP, couldn't think of one here
Block arrows: 270 or 360 degrees maybe? Dunno, BA3 is already pretty cool
The point of this is just that giving you some powers, while also keeping you from getting too OP because who would be able to unlock everything before dying? Might also add some strategy to the upgrades. I might have missed some trees
