Those vibrabombs sound like they're perfectly designed and balanced for FPS gameplay. Hopefully, different munitions are allowed (assuming that doesn't stray to far from the BT universe), keeping the same functionality, and being balanced by only affecting a certain weight class range. I could see distracting explosions going off in high traffic areas, and using that opportunity to blast said enemy from an unusual vantage point. But I'd be thrilled seeing the variations of BT standard landmines: high-explosive, gas, inferno or smoke ordinances, using vibrabomb mechanics.
