I really enjoy using claymores because they reward predicting enemy movement instead of relying only on gunplay. I’d love to see that playstyle expanded with more traps and tactical gadgets.
Things like tripwire alarms, motion sensors, sound decoys, remote cameras, or other nonlethal traps could let players bait, track, distract, and outsmart enemies.
It would be especially fun if different gadgets could work together, creating little setups or traps around objectives and buildings. I think this would add even more variety and emergent Battlefield-style moments to the sandbox without simply adding more weapons.
