Download Annelids: Online Battle APK 496.3 Free for Android

Annelids: Online battle hands you a worm, a fully diggable battlefield, and 47 weapons, then lets six players blow that battlefield apart in real time.

Annelids: Online battle is a 2D worm-combat action game from Czech indie developer Michal Srb (studio gdmt.cz), first released in July 2013 and still updated in 2026, now past 100 million Google Play installs under the package cz.gdmt.AnnelidsDemo. The core idea borrows from the classic Worms formula but runs in real time on a fully destructible terrain: you dig tunnels, collapse ceilings on enemies, and fight across 17 maps with 33 standard weapons plus secret and premium ones. It runs on Android 4.0.3 and up, works fully offline against AI, and supports online plus Bluetooth multiplayer for up to six players. You control one worm per round and win by out-positioning, not just out-shooting.

Fully destructible terrain turns every map into a weapon you can dig through

The terrain in Annelids is not a backdrop, it is the main mechanic, and roughly half of every match is spent reshaping it rather than shooting. Every tile of dirt can be tunneled, blasted, or buried, so the map you start a round with rarely looks the same 30 seconds later. This is the single point most competitor write-ups skip: they list the weapons but never explain that the dirt itself is the strategy layer.

Three things follow from that. First, digging is a movement tool. You can burrow straight down to escape a Bazooka shot, then pop up behind the worm that fired it. Second, dirt is cover you build yourself: the Dirtball weapon throws a lump of terrain you can stack into a wall, and worms (including the zombie AI) will pile dirtballs into towers to climb toward you. Third, the ground is a kill method on its own. Drop the ceiling of a tunnel on an enemy and you score a crush kill without spending a single bullet.

The maps push this further depending on layout. Open maps like Sea or Slopes give projectiles long sightlines, so a Sniper Rifle or Missile dominates. Tight maps like Labyrinth reward Drill users who carve private routes and Mine layers who seal chokepoints. Because maps are procedurally generated on top of the 17 fixed templates, no two Deathmatch rounds on the same map play identically. If you are coming from a static-cover shooter, the mental shift is this: the smartest move is often to change the terrain first and shoot second.

An arsenal of 47 weapons split across firearms, explosives, fire, traps, and melee

Annelids carries 47 weapons in total, 34 unlocked by default, 10 premium, 2 secret, and one special, which is more than double what most listings bother to name. The real skill is matching weapon class to terrain and range, so they break down into five working groups.

Firearms (hitscan and fast reload):

• Gun: fires one low-damage bullet with a fast reload, the safe poke when you have no sun for anything bigger
• Machine Gun and Uzi: chain several low-damage bullets, strong for chipping a worm pinned against a wall
• Shotgun: scatters pellets that lose damage over distance, best inside tunnels at point-blank
• Sniper Rifle: one high-damage bullet that produces heavy recoil, doubling as a recoil-jump boost across gaps
• Gatling gun and Hand Cannon: the high-end firearms, the Hand Cannon trading slow reload for one of the biggest single hits in the game

Explosives and projectiles: Grenade and Chiquita Bomb arc over walls and detonate on a timer, Cluster Bomb splits into smaller charges over a wide area, Dynamite plants a delayed heavy blast for trap setups, and Missile, Small Rockets, and Bouncing Rockets cover the ranged explosive role. Bazooka and Stun Grenade round this group out, with the Stun Grenade freezing a target instead of dealing damage so you can line up the finish.

Fire and area denial: Flamethrower clears grouped enemies and chews through dirt structures fast, Molotov Cocktail puts a burning pool on the ground, and Napalm releases scattering flames 1.7 seconds after it lands, ideal for sealing a tunnel mouth. Poison gas lingers as a cloud, and a recent weapon-interaction update even lets you set gas on fire or shoot mines remotely.

Traps and utility: Mine and Floating Mine guard chokepoints, Drill carves attack routes, Jetpack grants vertical escapes, Spiderweb pins a worm in place, and Dirtball and Balloon shape or block terrain.

Melee and secret: Axe, Sickle, and Baseball bat handle close range, while the secret tier (Laser, Energy ring, Phaser) is the prize for unlocking. The Energy ring is the standout: it blocks the direct impact of Grenade, Dynamite, Napalm, Cluster Bomb, Hand Cannon, and a dozen more, making it the closest thing to a panic button the game offers.

Six game modes from Deathmatch to a one-life Zombies survival run

Annelids ships six distinct modes, and the choice changes how aggressively you should reshape terrain, not just who you shoot. Most write-ups list mode names with no rules attached, so here is what each one actually demands.

• Deathmatch: free-for-all, every worm for itself, where digging escape tunnels matters more than in any other mode
• Team Deathmatch: two squads, so friendly-fire weapons like Bouncing Rockets and Mines become a liability near allies
• Capture the Flag: rewards Jetpack and Drill users who can move fast through dug routes instead of fighting head-on
• Conquest: control-point fighting where holding ground favors Mine and Floating Mine defensive layers
• King of the Hill: one zone to dominate, which turns the map center into a meat grinder for area weapons like Napalm
• Zombies: added on October 11, 2024, a one-life survival mode against waves where Flamethrower and Shotgun clear crowds, and Poison gas plus Stun Grenade are useless because zombies ignore those effects

The Zombies mode deserves a specific note because it flips the game’s usual logic. You get 10 seconds before the first wave, no respawns, and the zombies build dirtball towers to climb to you and wield Jetpack, Dynamite, and Axe of their own. Avoid Seeking Missile here, it will not lock onto zombies and behaves like a plain missile. Across all six modes, the offline single-player runs on AI strong enough to practice against, which is how most players learn terrain control before going online.

Online and Bluetooth multiplayer for up to six players, plus gamepad support

Annelids supports up to six players in one match across both online servers and local Bluetooth, with PvP and cooperative options, and that six-player cap is the number that makes the destructible terrain feel chaotic rather than tidy. Six worms all digging, planting mines, and collapsing tunnels turns a small map into a constantly shifting puzzle.

Online play is free and syncs your coins and progress to your account, so the weapons and maps you unlock on a phone carry to a tablet. Bluetooth mode covers the no-internet case, useful for local matches with friends in the same room. Recent updates folded in more stable multiplayer and better controls on Android TV, which matters because the game also supports MOGA and most Bluetooth gamepads. On a controller, the aim-and-fire timing is noticeably tighter than touch, and the Sniper Rifle recoil-jump becomes far easier to land. The 68-mission single-player campaign exists partly as a controlled space to learn each weapon before you bring it into a six-worm brawl where one bad Bouncing Rocket can clear your own team.

Version 496.3 update: stabler multiplayer, Android TV controls, and a smaller install

The 496.3 build focuses on multiplayer reliability and platform polish rather than new content. Pulled from the official changelog, the main changes are:

• More stable online multiplayer, reducing desync and freezes during fast weapon swaps
• Better controls on Android TV, tuning the gamepad layout for big-screen play
• Added languages, widening the menu and tutorial localization
• Reduced app size, lowering the download and storage footprint on older devices
• General bug fixes and performance improvements

For context on the content cadence, version 1.114.0 earlier added weapon interactions (setting gas on fire, shooting mines remotely), and the October 2024 update introduced the one-life Zombies mode. The 496.3 release continues the long-running pattern of small, frequent stability updates rather than large feature drops, which fits a 13-year-old title with an established weapon and map roster.

Annelids: Online battle MOD APK features

This MOD removes the coin grind and the locked-content walls that gate the secret and premium weapons, aimed at players who want the full 47-weapon arsenal and every map open from the first match instead of replaying missions to farm currency. It also strips the ads that interrupt the standard build.

Unlimited Coins

Coins are the single currency Annelids uses to buy weapons and unlock maps, normally earned slowly through the 68 missions and online wins. The MOD sets coins to a maxed value, so you can buy the Gatling gun, Hand Cannon, or a premium weapon immediately instead of grinding several mission runs per purchase. This matters most in the Zombies survival mode and harder online lobbies, where walking in without crowd-clear tools like the Flamethrower puts you at a flat disadvantage.

All Weapons Unlocked

The stock version locks 10 premium weapons behind purchase and hides 2 secret weapons (including the Energy ring and Laser) behind progress conditions. The MOD opens all 47 from the start, so the Energy ring shield, which blocks direct hits from Grenade, Dynamite, Napalm, and Cluster Bomb, is available in your first Deathmatch rather than dozens of matches in. For terrain play, having the Drill and Dirtball unlocked early changes how aggressively you can carve and wall off a map.

No Ads

The standard build shows ads between rounds and ties some bonus rewards to rewarded video. The MOD removes the interstitials entirely, so back-to-back matches in Deathmatch or King of the Hill run without the break, and any reward normally gated behind watching a clip is granted directly.

Frequently asked questions

Is the Annelids: Online battle MOD safe to install?

The MOD APK is a modified package, not the official Google Play build, so it carries the usual risk of any sideloaded file. Install from a source you trust, enable install-from-unknown-sources only for that file, and keep the original on a separate account if you play online. The anti-ban layer reduces but does not guarantee account safety.

Will the MOD get my online account banned?

Annelids syncs coins and progress online, so a server can flag maxed currency or all-weapon access that the account never earned. The included anti-ban lowers the risk, but the safest approach is keeping the MOD for offline missions, the AI campaign, and Bluetooth matches, and using a clean install for ranked online lobbies.

How is the MOD different from the stock APK?

The stock build makes you earn coins to buy weapons and unlock maps, and shows ads between rounds. The MOD gives maxed coins, opens all 47 weapons (including the Energy ring and the 10 premium ones) plus all 17 maps from the start, and removes ads. The actual combat physics and modes are unchanged.

Does Annelids work fully offline?

Yes. The 68-mission campaign and the AI-driven single-player run with no internet, and local Bluetooth multiplayer needs no connection either. Only the online multiplayer servers and cross-device coin sync require a network. The game runs on Android 4.0.3 and up, so older and low-storage phones are supported.

Is the game free on the Play Store?

Yes, Annelids: Online battle is free to download, with online multiplayer also free since an earlier update. Coins fund weapon and map unlocks, and 10 premium weapons plus optional ad-removal are the paid extras in the stock version.
