Krunker vs 1v1.lol: Browser FPS vs Building

Krunker and 1v1.lol both grew up in the post-Fortnite browser-FPS gap, but they sat in different parts of it. Krunker is a fast, pure first-person shooter inspired by Counter-Strike and the old Quake-style web games. 1v1.lol was a one-versus-one Fortnite-style shooter where you built ramps, walls, and roofs to control the fight. The krunker vs 1v1.lol question used to be simple: pure aim, or aim plus building?

Update: 1v1.LOL has shut down. Its developer, JustPlay.LOL, took the game offline permanently in early November 2025, and its Steam listing has been retired. This page now covers how the two games compared, and what you can still play.

What each game is

Krunker launched in 2018, created by Swiss developer Sidney de Vries under the Yendis Entertainment name, and was bought by browser-games company FRVR in 2022. It’s a browser FPS built on Three.js with a low-poly, voxel-flavored art style. You pick from a class roster (Triggerman, Hunter, Run N Gun, Spray N Pray, and more), each with a different primary weapon, and play team or free-for-all matches on a rotating map pool. The pacing is fast: sub-second time-to-kill, high movement speed, bunny-hopping for momentum, head-glitches for cover. Our Krunker review goes deeper.

1v1.lol launched in 2019 from JustPlay.LOL. It was a 1v1-focused FPS where every player could build Fortnite-style walls, ramps, floors, and pyramids. Maps were small. The default mode was exactly what the name promised, one player versus one player, with build battles deciding most fights. The studio later added 2v2, 4v4, party, and battle royale modes, but the 1v1 build-fight was the identity until the shutdown.

Core gameplay loop

Krunker’s loop is classical FPS: spawn, find an enemy, engage, kill or die, repeat. Map control matters. Class selection matters (a sniper plays nothing like an SMG). The skill ladder is aim, movement, positioning, and game sense.

1v1.lol’s loop was build-fight: spawn, meet your opponent, fight and build cover at the same time, edit pieces to open shooting angles, win or die. The build mechanic was constant. Almost no fight in 1v1.lol happened without building, and pure aim duels were rare.

Controls and input

Krunker uses standard FPS controls: WASD to move, mouse to aim, click to shoot, R to reload, space to jump (with bunny-hopping for movement tech), shift to crouch. The control surface is small and learnable in five minutes.

1v1.lol added a build layer on top: dedicated keys for each build piece (wall, ramp, floor, pyramid), a switch between weapon and build modes, and an edit key. Building speed was a major skill, and editing a placed piece to cut a window or doorway was the high-skill mechanic that separated good players from great ones. New players typically needed an hour with the keybinds before they could compete.

Maps and mode structure

Krunker has a deep map pool with community maps alongside the official set. Modes include Free For All, Team Deathmatch, Hardpoint, Capture the Flag, Parkour, and others. The community map editor keeps new content coming, so the game feels like a full multiplayer FPS with variety.

1v1.lol’s maps were intentionally simple: small flat arenas with minimal cover, because the cover you needed you were supposed to build. The simplicity was the point. The map shouldn’t decide the fight; you and your build skill should.

Skill ceiling

Krunker’s skill ceiling is in aim, movement tech, and positioning. Top Krunker players show the same skill set as strong Counter-Strike and Quake players: precise aim, bunny-hop momentum, head-glitch positioning, and a feel for when to push and when to hold.

1v1.lol’s skill ceiling was in build speed, edit timing, and fight-while-building muscle memory. Top-level play looked recognizably like Fortnite: fast walls to block incoming fire, ramp rushes for height, double-edits for surprise angles. Our 1v1.lol review covers how that meta worked before the servers closed.

Time-to-kill and engagement length

Krunker has a low time-to-kill. Sniper headshots are one-shot kills, and the SMG can drop you in under a second at close range. Engagements are short and decisive, and respawn is near-instant.

1v1.lol had a higher time-to-kill because building stretched engagements out. A fight usually involved shots traded across walls and ramps that went up and got edited mid-fight. Engagements often ran 10 to 30 seconds even in 1v1 mode.

Movement

Krunker has classic arena-shooter movement: high base speed, bunny-hopping for momentum, slide-jumping. Top players use movement to be hard to hit and to cross the map faster than the opponent expects. Movement is a real skill axis.

1v1.lol’s movement was simpler: walk, run, jump, crouch. Most of its “movement” happened through building, gaining height with ramps and blocking sight lines with walls, rather than through pure traversal.

Customization and progression

Krunker has a deep cosmetic system: weapon skins, character models, sprays, custom crosshairs. Some unlock through play, others through the in-game KR currency. Class loadouts are fixed within a class, but switching class is free.

1v1.lol sold cosmetics on a similar model. With the shutdown, those items and accounts are gone. Both games were fundamentally skill games where cosmetics didn’t change gameplay.

Audience and community

Krunker’s community leans toward competitive FPS players who came from Counter-Strike, Valorant, or older arena shooters and want a no-install browser option. It has ranked play and an active community map scene, though its audience is smaller than at its peak.

1v1.lol’s community skewed younger and overlapped heavily with Fortnite players, many of whom used it to warm up their building. That crowd has largely moved back to Fortnite itself.

Which one should you play now?

Krunker, because it’s the one that still exists. If you like Counter-Strike, Valorant, Quake, or arena shooters, its pure aim-and-movement loop is exactly what you want, and it still runs free in a browser tab.

If you want another live browser shooter, Shell Shockers (the egg FPS from Blue Wizard Digital) is a lighter, goofier option; see our Krunker vs Shell Shockers comparison. If what you miss is the build-fight, Fortnite is free to stream in a browser through Xbox Cloud Gaming. That needs a solid connection and is cloud streaming, not a native browser game.

Be wary of sites still advertising “1v1.lol unblocked” or downloadable copies. The official servers are offline, so those pages can’t give you the real multiplayer game.

Frequently asked questions

Is 1v1.lol shut down?

Yes. JustPlay.LOL shut 1v1.LOL down permanently in early November 2025, taking the servers, website, and in-game items offline. Mirrors or old app files can’t bring back the official multiplayer servers.

Is Krunker still playable?

Yes. Krunker is still online and free to play in a browser, with an optional Steam client. FRVR has owned it since 2022.

Was Krunker or 1v1.lol harder to learn?

1v1.lol had the steeper learning curve because of its build and edit mechanics. Krunker is easier to pick up, but its skill ceiling is just as high once you start optimizing movement and positioning.

Is Krunker pay-to-win?

No. Krunker monetizes through cosmetics. Skins and customizations don’t change weapon stats or movement speed.

What’s a good short-session alternative?

Krunker free-for-all matches are quick, and respawn is near-instant. For a genuinely short, no-aim break, the Chrome Dino game is the right pick.

The takeaway

Krunker vs 1v1.lol was the classic-FPS vs Fortnite-FPS question in a browser tab. Krunker rewarded aim and movement; 1v1.lol rewarded aim plus build speed. Since 1v1.LOL shut down in November 2025, Krunker is the one you can still load and play. For a no-shooter break between rounds, the T-Rex Runner is still one click away.
