Light barriers and/or pressure plates
So thinking about ways to solve the cheese-base vs. w-holders and speedrunners issue discussed in other threads rn i thought about light barriers and pressure plates. Could be a placeable for builders and linked with 1 maybe 2-x traps, or alarms to trigger guards, and could be upgradable. Super expensive capacity wise and heavily limited in amount you can place.
Would be visually hard to spot, especially if you go fast (there could be new equippables for raiders to help find/disarm them), but still would give warning and sounds of the traps triggered by them. Traps linked to them could only be triggered by them (they lose their current triggerfield or whatever) and still be destroyed like usual.
This way builders could make really fancy setups to catch people that just move through everything (imagine figuring out the right timing for these things, at least i would have fun doing that stuff) and make a slow and methodical approach safer/speed approach much more dangerous. I think that would also balance progression between the slower and faster dudes a bit (although raiders are not really in danger to lose anything besides competitive score).
(probably a bit late to implement something like that though lol)
