Gravity mod

Gravity Mod is a browser-based physics sandbox where you spawn objects, build and wreck things, and fight off enemies when you want some action. It was made by a developer called AutismDev and runs without a download, so you only need a desktop browser and a few minutes. This guide covers what the game offers, how the controls work, what “unblocked” really means, and what to do if it won’t load.

What Is Gravity Mod?

Think of it as a toy box with no instructions. You pick a map, open a spawn menu, and bring in props, tools and weapons. Then you build something, knock it down, or see what happens when physics gets involved.

If you’ve played Garry’s Mod on PC, the spawn-menu idea and the Nextbots mode will feel familiar. Gravity Mod is a separate, lighter browser game, though, not a version of it. One portal also notes that its maps are inspired by Half-Life 2.

What Does “Unblocked” Actually Mean?

“Unblocked” is a search habit, not a game feature. Many school and workplace networks filter game sites, so people look for pages that haven’t been added to those filters. A page labeled “unblocked” is simply one that happens to load on a given network.

That has two consequences:

• No guarantee. Whether this page loads depends on your network’s rules, not on the game.
• Follow your network’s rules. If a school or employer blocks games, playing during class or work hours can get you in trouble. This page doesn’t help you get around any restriction, and you shouldn’t use proxies or VPNs to work around a policy you’ve agreed to.

At home, or anywhere games are allowed, you can open the page and play.

Game Modes: What You Can Do

Portals describe the mode lineup differently. Some list three headline modes, while others count six in total. Check the menu in the version you’re playing, because the labels can change as the game is updated.

Sandbox

This is the main mode and the best place to start. There’s no objective and no timer, so you can spawn items, build structures, test ideas and see how the physics behaves. The game also reportedly has a camera feature for capturing your creations and an achievement system that unlocks new things to try.

Survival-style modes

When building gets quiet, these modes hand you weapons and send waves of enemies, including zombies, your way. The weapon variety ranges from silly to serious, so it’s worth trying a few.

Nextbots

Here you’re being chased rather than doing the chasing. The goal is to keep moving, find cover and avoid getting caught. If you like tense, short rounds, this is the mode for you.

Controls and the Spawn Menu

Controls can differ slightly between portals, so treat the in-game pause or controls panel as the final word. These are the basics reported by sources that list them:

• Move: W, A, S, D
• Switch weapons: number keys 1 to 6
• Other actions: shoot, jump, run, crouch, reload, use items, switch player model, free camera, pause, and open the spawn menu

The spawn menu is the most important control. It’s where objects and add-ons come from, so open it early and browse before you start building.

First 15 Minutes: A Simple Starter Plan

1. Start in Sandbox. Learn the movement and camera without any pressure.
2. Open the spawn menu and try one of everything small. You’ll quickly see what behaves like a prop and what behaves like a tool.
3. Build one thing, then break it. A tower or ramp works well, and it teaches you how physics objects interact.
4. Try a weapon on your structure. Cycle through the weapons with the number keys.
5. Then try a survival-style mode. You’ll already know how to move and switch weapons, so you can focus on the enemies.
6. Save Nextbots for last. It’s easier once you know the map and your movement.

Game Not Loading? Quick Fixes

• Refresh the page.
• Do a hard refresh with Ctrl + Shift + R (Cmd + Shift + R on Mac).
• Close extra tabs. 3D browser games can use a lot of memory.
• Try a current version of Chrome, Edge or Firefox, and make sure WebGL is enabled.
• If it still fails, the game may be blocked on your network. See the section above.

Is Gravity Mod Suitable for Everyone?

The game includes weapons and combat against zombies and other enemies. Ratings vary: one portal lists PEGI 16, another lists 18+. I’m not aware of an official ESRB rating. Parents should judge for themselves by trying Sandbox first and watching a bit of the survival modes.
