Grom is currently S-tier in Heist with a score of 86/100. As a Thrower, Grom deals damage over walls and denies zones without needing line of sight, making it a reliable pick when the meta favors Heist.
Run Foot Patrol as the default Star Power for Grom — it works in most situations. Switch to X-Factor on maps that punish your main weakness. For Gadgets, Watchtower is the standard active pick; Radio Check is situationally better on specific map types. Speed and Shield Gears are the standard choice.
Grom struggles against Mortis and Leon, who can out-trade Grom at the ranges or map types where Grom is most exposed. On the flip side, Grom consistently beats Bull and El Primo.
Grom performs best in Heist (S-tier, 86/100). The Thrower kit — deals damage over walls and denies zones without needing line of sight — is directly rewarded in Heist, which is why Grom climbs higher here than in other modes. See the mode ratings section for a full breakdown.
Grom pairs best with Gale and Emz. Since Grom deals damage over walls and denies zones without needing line of sight, teammates that cover the opposite role — whether that is frontline presence, healing, or ranged poke — create the most complete comp.
To play Grom well, focus on Heist where the mode rating is highest, and lean into being a Thrower that deals damage over walls and denies zones without needing line of sight. Run Foot Patrol as the core build, track Mortis and Leon on the enemy team, and pair with Gale and Emz when possible.
Grom fires a single high-arcing shell that detonates on impact and sends three smaller bomblets outward in a circle, covering a large area with explosive splash damage. His Super launches a devastatingly large bomb that destroys walls and covers nearly the entire width of a lane, one of the most powerful zone-clear abilities in the game. He thrives in Heist and Gem Grab where his long arc range allows him to attack from behind maximum cover.
Grom's main attack arc is very high, so mentally trace the trajectory before firing to place the center impact and predict where the three secondary explosions will scatter. His Super wall-destruction ability is most valuable early in Heist to clear cover from the enemy safe approach.
GROM DEEP DIVES
Mode-specific stats and the top ranked Grom players globally. Each page shows win rate, pick rate, best maps and tier for that specific combination.
Find a wall that puts you behind cover while arcing into the enemy's path. Do not leave that cover unless your target is out of reach. Take Foot Patrol in most situations, switching to X-Factor on maps where enemies can close distance. Your damage is free if enemies cannot reach you.
PRIORITY
Draft Around Counters
Watch for Mortis or Leon. Both Watchtower and Radio Check are in your kit — learn which one punishes your counters versus which gives you an escape window. Use your Gadget early rather than saving it for a desperate moment.
MATCHUP
Best Team Shape
Pair Grom with Gale or Emz when possible. Build toward Grom Bomb Goes Boom! in safe positions — it swings fights instantly, so activate it when your team has the edge, not when you are already behind.
