SLADE3

Overview

SLADE3 handles both archive management and editing individual assets. It can create, open, save, import, export, reorder, convert, and revert archive resources, with multiple archives open in tabs for copying and pasting between them. Batch extraction and archive repacking also help with larger asset collections. This breadth is useful when a project spans several resource types, though users who only need a narrow extraction task may not need a full editor.

Its archive support covers Doom WAD and ZIP/PK3, Quake PAK and WAD2, Build GRP and ART, Shadowcaster DAT/LIB, and Amulets & Armor RES, among other formats. It also supports formats such as BSP, GOB/LFD, RFF, HOG, and POD, plus multiple model and texture formats. That makes it capable across a broad range of game-resource files, but does not change its core orientation toward Doom-engine games and source ports.

Key features

Maps and text

The map editor works with Doom, Hexen, and UDMF maps, and includes 3D editing, automatic sector generation, and advanced source-port features. Level creators can work on maps alongside the archives and assets they depend on. The text editor adds syntax highlighting, function calltips, autocomplete, auto-indent, and find-and-replace, useful for editing project text without leaving the application.

Graphics, textures, and audio

Users can view and convert graphics, remap palettes, and export images to PNG. SLADE3 can also edit Doom composite textures, including ZDoom texture definitions. Its audio player handles MUS, MIDI, XMI, HMI, HMP, and other audio formats, so it can inspect sound resources as part of the same workflow.

External tools and release choice

ACS compilation depends on the external ACC program. PNG optimization likewise uses external tools: PNGOUT, PNGCrush, and DeflOpt. These integrations extend the workflow, but require users to bring the relevant programs rather than relying on SLADE3 alone.

The latest stable release is 3.2.12 for Windows, Linux, and macOS. Version 3.3.0 Beta 2 is also available on those platforms, but beta builds may have bugs, crash, or contain unfinished features. For work where reliability matters more than trying newer changes, the stable release is the sensible choice.

Pricing

SLADE3 is free. The free desktop editor includes the archive, map, text, graphics, and audio capabilities described above; there are no paid tiers or plan limits to weigh. The developer accepts optional donations, and the project is GPL-2.0 licensed.

Platforms

SLADE3 is available for Windows, Linux, and macOS. Both the latest stable release and the latest listed beta support these three desktop platforms.

Who it's for

SLADE3 is best suited to Doom-engine modders and level creators who want one desktop application for archives, maps, textures, graphics, text, and audio. Its format range also benefits people handling resources from several older game ecosystems. It is less appropriate for users seeking a universal editor for unrelated games, or anyone unwilling to work around the external dependencies used for ACS compilation and image optimization.

Pros and cons

• Pros: Broad archive operations, including repacking and batch extraction, make it useful for more than file browsing.
• Pros: Map editing, text tools, graphics and texture support, and audio playback cover several stages of a Doom-engine project in one application.
• Pros: Free on Windows, Linux, and macOS, with no paid tier or seat and quota limits to manage.
• Cons: Its focus is Doom-engine games and source ports, so it is not a general solution for every game-modification project.
• Cons: ACS compilation and PNG optimization rely on external programs, adding setup work for those workflows.
• Cons: The newer beta may contain bugs, crashes, or unfinished features; users prioritizing stability should use the stable release.

Alternatives

For a wider set of game asset tools, browse Game Asset Extractors. AssetRipper is a freemium option with a free plan and a $10 per month premium plan, suited to readers comparing free access with a paid tier. Source 2 Viewer is free, open source, and available on Linux, macOS, Windows, and the web; choose it when that platform mix is a better fit. Rusted PackFile Manager is a free option for readers who prefer an MIT-licensed tool. OpenKH is another free choice, with Apache-2.0 licensing and a .NET 8.0 Runtime requirement. QuickBMS is a free, open-source, multiplatform tool. UABEA is a free option for Linux and Windows. Crowbar is free and Windows-only, with optional donations. VPKEdit is another free alternative.

Verdict

Choose SLADE3 if you make Doom-engine content and want archive handling, map editing, and several asset tools under one roof without paying. Its breadth is the main reason to pick it; its narrow game focus and reliance on external utilities are the main reasons to look elsewhere. For dependable use, prefer stable 3.2.12 over the beta.
