The world looks like an obby, all blocks and bright grass, and then you look down the iron sights. Obby: Duelists Online is a free blocky first-person shooter you play in your browser. You run, slide and jump through blocky arenas with 4 weapon slots, a grenade and a quick melee strike, outgunning other duelists.

How It Works
Obby: Duelists Online puts you in an arena in first person with a gun up. WASD runs, Space jumps, and the crouch key does double duty: press it standing to drop low, press it at a run and you slide. Left click fires from the hip, right click brings the sights up, and R reloads.
Your kit sits on 4 weapon slots, picked with the number keys or the mouse wheel, and 2 extras have their own keys: F for a quick melee hit and G for a grenade, so neither needs a weapon swap. Tab pulls up the scoreboard. The Obby: Duelists Online game keeps its exits deliberate: Esc only releases the cursor, and the gear icon holds settings and the way back to the hangar.
- Run with W, A, S and D and jump with Space.
- Hold RIGHT MOUSE to aim and click LEFT MOUSE to fire.
- Press 1 to 4 or spin the wheel to change weapons.
- Throw a grenade with G or strike up close with F.
- Press R to reload once the shooting stops.
- Press TAB to check the scoreboard between fights.
What Makes It Stand Out
- A real shooter in a blocky world. Hip fire, aimed fire, reloads and grenades.
- 4 weapon slots. Keys 1 to 4 or the mouse wheel.
- 2 off-hand moves. F melee and G grenade fire without switching weapons.
- A slide. The crouch key at a run turns into a slide.
- 2 crouch keys. C or Shift, so either hand position works.
- A hangar between matches. The gear icon leads there.
Getting Started
- Pick Shift or C and stick with it. Obby: Duelists Online binds crouch to both, and Shift sits next to WASD, so sliding never means letting go of W.
- Slide into cover, not across open ground. The slide only triggers from a run, so it's a way to arrive low behind a block.
- Use 1 to 4 in a fight and the wheel out of one. A number key lands on the exact slot; the wheel can roll past it.
- Learn where Esc stops. Esc releases the mouse and nothing else, so a panicked press leaves you in the match with no aim.
Going Further
The fastest way to win close fights in Obby: Duelists Online is to stop reloading inside them, because F's quick melee is already on a key and a reload at arm's length hands the other side a hit. Grenades are for corners, not faces: G needs no weapon swap, so a grenade over a block wall costs almost no time and flushes a camper out. Aimed fire and the slide pull in opposite directions, since right click slows the moment down and the slide speeds it up, so pick one per engagement. The scoreboard is for between fights, not during them. Settings and the hangar sit behind the same gear icon, so fix your settings before a duel starts rather than opening that menu in the middle of one.
Mistakes Worth Avoiding
- Reloading at close range. The other duelist gets a shot while F was right there.
- Pressing Esc to leave. It only releases the mouse; the gear icon is the exit.
- Sliding from a standstill. It's just a crouch.
- Scrolling for a weapon under fire. The wheel can overshoot; 1 to 4 cannot.

Final Thoughts
This is a proper shooter wearing an obby's clothes, and the slide is the best thing about it. Skip it if the word obby brought you here for jumping puzzles; the jumps exist to dodge bullets. Play Obby: Duelists Online online for a few matches and you'll know whether the blocky look is charm or distraction.
