So then just buy them as regular explosives, that are triggered to detonate as soon as anyone steps within the effective blast radius of the explosion. I wouldn't worry about balancing in a CP cost to make it "fair."

- a super-agent's car that deploys an oil slick and caltrops to deter the relentless pursuit of a paternity suit lawyer
- a coil of barbed wire you stretch across the dorm floor to keep that smelly roommate away from your fridge
- a bear trap set in the path of a rampaging politician
- a Death Submarine with a hull that can be electrified to fry PETA protesters
- a smoke grenade deployed by a trooper to provide cover and sneak away from the dreaded PowerPoint safety briefing.
- a barrel of radioactive waste you pop open at a family reunion just for shiggles
I don't see why you can't just buy things as field hazards and then just poop em out when you need to. They function almost exactly like weapons with size and all. Here's your examples converted:
-Caltrops are a concealed hazard, oil slick is just difficult terrain. The bonus of an oil slick is that once a creation enters it, it can't change directions until it leaves!
-Barbed wire is technically a concealed hazard, though you can see it. slow-moving figs can pick their way through it without taking damage (or simply cut it).
-Bear traps are straight-up exposure damage. You step on it, you take 1d6 damage.
-An electrified death sub is also exposure damage. Consider d8s if you have em!
-Smoke grenades are something lots of us have trouble with coming up with something cool for. Some of us say it should just grant cover to everyone within a certain radius, but that's both easy to forget about, and doesn't look very cool. Another idea is that you get to place something like 1d20 studs' worth of blocks and "construct" a smoke wall that loses a few bricks every turn as it dissipates. If you come up with something else, it might even be cooler!
-Spill that radioactive waste, and that whole puddle is a sick-ass exposure hazard. use WISG rolls to determine any awesome mutations.
