Hazmob.io

Hazmob.io is a browser FPS that strips away all the nonsense and just throws you into fights that end fast. You pick a mode -- Team Deathmatch, Free-For-All, or Search & Destroy -- and then you're dropped into a small, tight map like Dust2 or Aztec with other players. The whole thing runs in your browser, no download, and somehow the netcode is decent enough that you can actually land shots. Movement is WASD, jump with space, left click to shoot, right click to aim down sights. V also aims if you prefer that. Shift to sprint, C to crouch. The controls are snappy and responsive, which matters because you die in two or three bullets most of the time.

The core loop is simple: spawn, grab a weapon, find enemies, shoot them before they shoot you. But there's more to it than that. Weapons spawn on the map at fixed points -- you'll see an AR, a shotgun, a sniper rifle, sometimes a rocket launcher. You press G to pick up whatever's on the ground, and you can only carry one main gun plus a pistol. Ammo is limited, so you're constantly moving toward the next pickup or scavenging off dead bodies. That creates natural chokepoints and fights over weapon spawns. The maps are small enough that you're never running for long. Dust2 has that long corridor where snipers camp, Aztec has the bridge everyone fights over. Both are good.

What gets tricky is when players start using skills. You press 4, 5, or 6 to activate abilities like a health pack, a speed boost, or a smoke grenade. E and Q are for alternative skills that vary by class or loadout -- some people run with a flashbang, others with a damage buff. You have to manage cooldowns and choose when to pop them. A well-timed speed boost lets you close distance on a sniper, but if you waste it early you're just a slow target. Crouching reduces your hitbox but slows you down, so it's risky. Jumping while shooting ruins your accuracy -- don't do it.

Difficulty ramps up because the lobbies get sweatier as you win more. There's no visible rank, but matchmaking seems to pair you against people with similar kill/death ratios. After a few wins, you'll face players who slide-cancel and pre-fire corners. That's when the game becomes about map knowledge and reaction time. You learn where people hide, which angles are safe, and when to sprint vs. walk. The satisfying moments are those tight 1v2 clutches in Search & Destroy where you outplay two guys by baiting them into swapping weapons and then catching them mid-reload. Or hitting a clean headshot across the bridge on Aztec with the sniper -- that feeling is why you keep coming back.

Weapon handling matters. Each gun has a spray pattern and recoil -- the AK is strong but kicks hard, the M4 is more controllable but does less damage. You can pick up guns from dead players, so the meta shifts based on what's available. Some players just run around with the shotgun, which is annoying up close but useless at range. Others camp with snipers. Free-For-All is chaos, Team Deathmatch has some structure, Search & Destroy requires patience and teamwork. You can also press P to see the leaderboard and check who's carrying the team. There's no progression system or unlocks -- what you see is what you get. It's pure mechanical skill.
