Rivals is the game that proved Roblox could hold a genuinely crisp first-person shooter, and the crowd has followed: about 206,000 players were in it as of August 31, 2026, on roughly 17.8 billion lifetime visits. What it sells is speed without clutter — small team fights and one-on-one duels, weapons that behave predictably, rounds short enough that losing one costs you ninety seconds of pride. Nobody leaves Rivals because it broke. People look for more games like it because one specific part of it hooked them: the gunfight itself, the duel format, or simply the joy of fighting other players in a fair arena. Those are different pulls, and they lead to different games.
The gunfight, kept honest
Arsenal is the closest thing to Rivals' elder sibling: a fast arena shooter running since 2015, built around the gun-game rotation where every kill swaps your weapon and the race is to the end of the list. It teaches the same lesson Rivals does — hit your shots, keep moving — but with a rotating armory instead of a chosen loadout, and its rounds are even shorter. About 3,200 players were in it as of August 31, 2026, a quiet shadow of its peak but enough for instant matches. Phantom Forces is the deep end of the same pool: the platform's long-running serious FPS, with a large rank-unlocked weapon catalog, bigger maps, and a slower, positioning-heavy rhythm. If Rivals feels like an argument settled in ten seconds, Phantom Forces is the version where the argument has terrain; around 2,200 players were in it the same day. Counter Blox adds the one thing neither has — an economy. Its rounds are Counter-Strike in miniature: buy phases, one life per round, a bomb site to take or hold, and the specific tension of knowing a lost round makes the next one poorer. It held about 1,400 players as of August 31. And Bad Business deserves naming with an honest caveat: mechanically it is the nearest match on the platform to Rivals' movement-forward gunfeel, but only around 140 players were in it as of August 31, 2026, so treat it as a museum piece worth one evening rather than a new home.
The duel
Rivals' duel queue is a reflex test with a scoreboard, and two games distill that test past the point of needing guns at all. Untitled Boxing Game, at about 13,800 players as of August 31, 2026, is one-on-one timing in its purest form — feints, blocks, counters, and fighting styles that change the shape of the exchange. Wins there feel exactly like clutching a Rivals duel: you read a human being and punished them. Blade Ball turns the duel into a group elimination — one accelerating projectile, a deflect window that shrinks as the rally goes on, and abilities layered over the top. It is timing rather than aim, but the skill curve scratches the same itch, and with about 25,200 players in it the lobbies fill instantly.
The brawl, guns optional
Some Rivals players discover the guns were incidental — what they wanted was fighting other people. The Strongest Battlegrounds is where that instinct goes on Roblox, and at about 68,600 players as of August 31, 2026, on more than 19 billion visits, it is one of the platform's biggest games of any kind: melee combo strings, ragdoll physics, and a public-lobby duel culture where fights start with a look. Jujutsu Shenanigans is the ability-kit version — Jujutsu Kaisen movesets, combo routes that take practice, arenas that break under the fight — and it was even busier the same day, around 130,000 players. Combat Warriors is the harder-edged loadout take, mixing melee and ranged weapons with high damage and little mercy; about 2,000 players were in it as of August 31. All three trade Rivals' clean symmetry for expression: you win with a route you practiced, not just a crosshair you settled.
Team fights with something to defend
Roblox BedWars gives the team fight a spine that pure deathmatch lacks: a bed to protect, resources to gather, gear to buy, and bridges to build toward the enemy. It is the pick for players who like Rivals' team modes but wish a round could build toward something, and about 36,000 players were in it as of August 31, 2026, on 11.6 billion visits. Criminality drops the round structure entirely — a dark freeform city where weapons are bought, fights are ambushes, and the stakes are whatever you were carrying. It is the least Rivals-shaped game on this list and the right answer for a specific player: the one who wants gun PvP with consequences instead of a scoreboard reset. Around 2,400 players were in it the same day.
How to choose
Name the thread. If it is the gunfight, Arsenal is the fastest yes, Phantom Forces the deepest, Counter Blox the most tactical. If it is the duel, Untitled Boxing Game is the purest read on another human. If it is the brawl, The Strongest Battlegrounds has the crowd and Jujutsu Shenanigans has the toolkit. If your team fights need stakes, BedWars builds them. Player counts above are single-day snapshots from the official Roblox games API and will drift; what each game is built around changes far more slowly. The wider shelf lives on the fighting and PvP genre page and in the directory, the anime-combat side of it continues in Roblox games like Blox Fruits, and Find games like your favorites shows how to keep pulling the thread from whichever pick lands.
