So here's some ideas that we came up with!
Shaped charges - explodes in one direction so as to not damage your walls. The idea is to reduce the 7 tile 'no-mans-land' between the mine field and your walls.
Landmine research - Just like bullet damage research. I'm not a fan of the idea as it doesn't make much sense (how do you get more boom without adding more explosives?).
"Mk2" landmines - Bigger more powerful landmines. They should have the same radius for gameplay reasons, but do much more damage. Bonus points if the sprite is bigger so they take up a full tile or more.
Claymores - Explosive traps that are triggered remotely somehow. No idea how fun or useful it would be, but it was suggested. Perhaps a wire condition if a turret is engaging an enemy? Could be fun if used in the style of the Discharge Defense.
I have searched the suggestions boards for other ideas, but came up empty. I encourage other ideas to be added to this thread. Thank you.
