I’ve played around a bit with UE4 and created some objects that transform into destructible meshes (add gravity, set impact strength really low and once it hits the ground it shatters). However, I knew the size and shape of the objects beforehand, so I’m guessing it adds a bit (ok, maybe a lot) more complexity to it when you have a custom laser-drawn shape like that. This could definitely be used as a digging tool. It could probably only work on certain types of rock so you can find valuable ores. Seeing this is sci-fi, you could also probably have an enemy that is made of rock and this is the tool you’d use to defeat or maybe just incapacitate so you can kill him. Could also be used to take down enemy ships. Could make it interact with different materials. This rock melts, this one reflects, this one is unaffected, and possibly it can also be used to melt certain rock to collect the molten form of the material.
I could see this working well in DRG if the destruction was a bit less and the magma effect was longer. Swarm coming? Melt the ceiling in their direction and they’ll have to walk through a shower of molten rock. Dreadnought chasing you? Make a trail of molten rock that it’ll have to walk along. Just don’t make it a special gun that you can only find like 12 energy cells (or whatever the ammo is) through like 10 hours of gameplay. This would be a gun I would want to experiment a lot with, not keep it in my backpack for the moment I really need it, and never use it. This has happened to me so much lol.
