EMP Grenade: Stuns and deals damage to all living things withing it's blast radius, but a useful trait is stopping machinery (aka cars, possibly boats, and other player operated stuff) for a while.
Incindary grenade: Acts like the Molotov, except it spawns only the orange fire and it has a larger radius.
Radial Claymore: Acts like a mine, but when triggered, it shoots 8 bullets outwards. It also has an activation gani where it bounces up from the ground, then the mine explodes. Inspired by the real life S-Mine used by the Germans in WW2.
Nano-Bots: Is a non-Valentines version of the Heart Bomb. Instead of a heart as the radius, has a transparent blue circle.
False Heart Bomb: Instead of healing your teammates, it saps the health of people not in the gang you're in, and regenerates your health with their stolen health.
Non-bomb idea: The defuse device. Allows you to defuse live planted mines, but only affects mines within a small radius. Doesn't affect traps or caltrops. Also has a GUI where you have to cut a certain wire to defuse the bomb.
