VOXEL ARENA WARFARE — free · no install · phone or desktop
🖱️ CLICK TO FIRE — FOUR IN THE CHEST DROPS THE BOT. OR JUST DIG THE ISLAND APART.
BlockStrike is a full arena shooter built out of voxels: procedurally generated worlds you can mine and build in, and Call of Duty gunplay on top of them — sprint, slide, ADS, recoil you can learn, killstreaks that arrive by air.
16 hand-tuned themes — snow, dunes, volcanic, nether, sky castle, the end — and 23 kinds of structure (houses, keeps, warehouses, bunkers, mineshafts) rolled fresh from a seed. Two players typing /seed compare maps; the whole room fights the same one.
Sprint, slide, jump, ADS with a 60% look slow-down. Recoil is a view offset the gun wears and bleeds back, bloom grows per shot, air costs 3.2× accuracy — and the reticle gap is the cone the bullet flies on.
Keyboard and mouse, gamepad, or thumbs: touch controls with a trackball-style flick, a layout you can drag into place, and per-device sensitivity shown in cm/360° so you can calibrate it like you mean it.
Knife, M1911, SPAS-12, .50 cal, frag — plus four activated specials you buy with coins and switch on for thirty seconds: GATLING GUN, LASER BEAM, SEEKER ×5 and WOLF PACK.
A suppressor is ribbed. An 8× scope is a tube with a bell. A drum is a disc. Click a part and mountAttachments re-measures the finished gun and seats it on the right rail — so the thing you fitted is on the thing you are holding.
The arm adds its own loft and the dotted arc under the reticle is drawn from the same function the grenade flies — so the line can't lie about where it lands. 26 m/s, 3 s fuse, and a level chuck puts it ~32 m out.
CTRL while sprinting is a slide.
Hold or toggle. Scopes slow your turn — as they should.
One gesture per weapon keeps the arcs honest.
First person or over-the-shoulder, any time.
Kills aren't the only currency any more: flag captures, banked diamonds, waves held and a minute on the hill all pay into the same counter, fractions carried and never rounded. Cross a rung and the game offers you the reward — no timer, no auto-pick, and the fight never stops.
Pick it on the CHARACTER screen's KILLSTREAKS tab and the slot lights up when the rung lands. Leave a rung empty and it simply asks you in the match — rewards on screen, no countdown, movement and trigger still live.
The 3-kill rung hands you a pet that hunts on its own — it walks the map, bites what it finds, and levels up as it kills: two kills a level, three levels, faster and harder each time.
Loyal, fast, first into the fight you started.
Type "build a house", "a castle", "make mountains", "dig a bunker" — a crew of up to seven bots walks to the site, lays every block and stops when the job is done. Try it right here:
Connect an OpenAI-compatible model — Ollama, llama.cpp, LM Studio, Jan, or any cloud endpoint with a key — and the model only answers sentence → small JSON. The rules expand that into geometry, unknown templates fall back, coordinates are clamped into the level. A hostile or broken model's worst outcome is a plan the rules refuse.
A user uploads an image and the bot builds/replicates the image into block art: a vision model answers with one line — "a long low white yacht with a raised cabin and a tall mast" — and that line takes the ordinary sentence path, so the crew raises what the picture shows. Asked for almost nothing on purpose: a model deliberates in proportion to what you ask it to hold. The image is downscaled to 448 px and sent only when you press the button.
The built-in vocabulary is a table, not a model, so a crew splits the same placement list every time. No server, no key, no network — it works on a plane, and it works on a phone.
A 128 × 48 × 128 voxel volume you fly through, paint into and play — then publish to the world. Below is a mini version you can actually paint in: pick a block, click the ground, shift-click to carve.
HOST BUILD opens a room: the host owns the grid, a build frame ships chunked level data to everyone, and every builder's strokes land in the same world. A joiner with nothing sends an ask and receives the map. Refresh and you keep the room — the relay remembers which browser it seated.
PUBLISH runs the same validator the game uses — no spawns, a spawn walled in, a map that isn't a map: refused. Pass and it appears under USER-CREATED in solo, and in a host's USER MAP dropdown online, thumbnail and author included — so even a joiner without the level sees the layout before the blocks arrive.
SETTINGS carries BLASTS REMOVE TERRAIN. Turn it off and every explosion — frags, mines, rockets, killstreaks — still hurts bodies but stops carving blocks, so a private match can't end in a moonscape.
Buildings follow the map: timber cabins with snow roofs on TUNDRA, concrete blocks with metal lintels on URBAN BLOCK, adobe with a brick frame on DUNES, stilted plank decks on ARCHIPELAGO. Around thirty chests a map, buried bunkers, mineshafts, rails, nether portals, boats — and a sky that is a pure clock, so the whole room gets the same weather. (A seventeenth, THE DARK FIELD, is where LIGHTS OFF plants its board.)
Iron and gold veins run under solid ground on every map. Whatever you mine banks to your profile and comes back as material at the bench.
Lava pools carve the map, water cancels a fall completely, fire is a cell that lives nine seconds and rolls into what's next to it.
Tracks are tunnelled and re-laid as structures arrive; minecarts have one degree of freedom; a lit portal takes 3 seconds and three or more lit frames make every destination random.
Every mode runs on a brand-new procedural map, and every mode is played headlessly by a test harness before you ever see it — because a mechanic can be correct and the mode still unplayable.
Clear the board before the clock — zombies walk in from the four gates while you do it. Level 1 is 3×3; every level after is two tiles wider under a tighter clock.
What a body is doing is priced as you do it: the corner prints the delta — EARNED 40 XP · 12 ⛃ — naming which half moved, and says nothing at all when the worth has not moved. It is hidden for a match that banks nothing, and again the moment a menu comes up.
The results screen carries the payout as rows — KILLS, OBJECTIVE, BLOCKS MINED, then VICTORY or THE FIGHT — and the level row is drawn apart from them, because those coins were earned by the level and not by the kills it would otherwise sit under. The headline is the fight's take plus what crossing a level paid, so a player who levelled up reads a number that matches their balance rather than one smaller than it.
A hundred levels, thirteen ranks over them at deliberately uneven spacing — RECRUIT at 1, SERGEANT at 18, WARLORD at 100 — and the bar under the card shows the next one (or says so when the ladder is finished). Level gates what the loadout can carry, so a match you lose still moves the rank that unlocks the next thing; the character screen carries the same receipt and names what the balance can now afford: IN REACH — the nearest thing, not a count.
There is no store: every gun, every attachment, every tool, every block is made at a 3×3 bench from material you mined. The book is tabbed and every tab prints ready/total, so "what can I build right now" is one number, not a scroll.
The rung is the tool's budget: a wooden pickaxe is 80 uses, obsidian 1,200. Damage crawls where durability climbs — and gold is the one rung off the curve: it hits harder than iron and dies sooner, which makes it the only real choice on the ladder.
A spent pickaxe comes back spent, with its hotbar cell empty until you fix it. MEND prices the repair in the tool's own material — one block per quarter — so mending early is cheap and letting it break is nearly a recraft.
A room code syncs lobbies across tabs and across networks through a relay — with a shared seed, so everyone fights the identical procedural map, or the host's own published level. Spawn into a match in flight and you get a short hold, not a head start.
Solo play, the editor, a room on this device and a self-hosted relay stay free. Online play on the official relays is $1.99/month — and free play never depends on it.
The browser game needs nothing: no install, no account, no key. But there is one thing a tab cannot do, and the desktop build does it — it runs the model itself. The installer carries llama.cpp's runner, and the LOCAL AI box grows an ON DEVICE (THIS PC) block whose weights are a download you choose.
llama-server ships as a sidecar: one pinned llama.cpp release, each archive checked against the SHA-256 GitHub publishes for it before a byte is unpacked, and only the files the runner actually loads are kept. It lands beside the executable, because ggml's backend scan looks in the executable's own directory and nowhere else — a bundle that got that wrong starts, loads every library, and then refuses every model.
Multi-gigabyte weights cannot be an installer anyone sane publishes, so the panel offers three rungs and fetches the one you pick — weights and vision projector together: QWEN3-VL 2B · 1.9 GB, 4B · 3.3 GB (the default) or 8B · 6.2 GB. Stopping mid-fetch keeps what arrived (RESUME · 1.4 GB left), and a finished file is checked against the hash it was pinned to before it is kept.
The runner comes up on a loopback port with a key minted for that port, and the panel then fills SERVER and MODEL and presses the ordinary CONNECT — so an on-device model reaches the crew through exactly the path Ollama does, and is special-cased nowhere. Downloaded once, it answers with the network off. No account, no key, no prompt leaving the box.
The panel asks what the box actually has — total RAM, what is free right now, cores — and recommends the largest rung that fits with a gigabyte of headroom, saying out loud what it found: 16 GB RAM · 9.1 GB free · 16 cores. This build's runner is the CPU one, so the line ends cpu only · no gpu backend in this build rather than leaving you to wonder why the graphics card is idle.
Both carry the identical game and the same runner. Slim (~57 MB) carries Microsoft's WebView2 bootstrapper, so a machine missing the runtime fetches ~1.5 MB once; offline (~259 MB) carries the whole runtime installer, for a box with no runtime and no internet. The install is per-user, so it never asks for administrator rights — and until the builds are code-signed, Windows will show SmartScreen's warning on the way in.
Open the tab, pick a mode, and see how long the bots let you live. Then go make a map and hand it to seven friends.
