Operating system Cross-platform

SLADE (SlayeR's Leet-Ass Doom Editor) is an open-source WAD editor capable of managing the lumps of WAD and PK3 files and of editing maps. It allows the user to view and edit sprites, textures, flats, sounds, SOCs, Lua scripts, level headers, and any other type of lump. In previous versions, SLADE was a map editor only, while a lump editor called SLumpEd was developed by the same author. The current version, SLADE3, is a merger of the two with many additional features. A configuration file does exist for Sonic Robo Blast 2[1], however it is only available on Windows for the time being.

When creating custom characters, it may be easier to downgrade to version 3.1.13, as more recent versions do not allow duplicate sprite names in PK3 files. However, this can be worked around by placing those sprites into subfolders.


SLADE requires the 32-bit Microsoft Visual C++ 2015 Runtime (choose VC_redist.x86.exe at the download page) to be installed. If you use the SLADE installer, it will automatically download and install the runtime for you, otherwise you will have to install it yourself.

After installing and opening SLADE, you will have to point SLADE to SRB2's base resource, which is srb2.pk3. In the menu bar, select "Editor → Select Base Resource Archive". Click on "Add Archive" and navigate to your SRB2 directory. Select srb2.pk3, then click OK, after which it should appear in the "Base Resource" dropdown box on the right side of the toolbar. Next to it, there is a box where you can choose your palette. The "Sonic Robo Blast 2" option is v2.2's palette, while "Sonic Robo Blast 2 (legacy)" is used for SRB2Kart. The "Existing/Global" option will also make SLADE use v2.2's palette, as long as srb2.pk3 is selected as the base resource.

When working on custom characters in WAD files, the following settings are recommended: select Editor → Preferences in the menu bar and uncheck the "Force uppercase entry names in Wad Archives" option in the Editing tab, which allows creating lowercase lumps. In the same tab, check the "Use percent encoding if needed outside of Wad Archives" option, which is necessary to create lumps with the ^ character in their names.

Differences to XWE

  • SLADE doesn't automatically convert images to the palette upon importing them like XWE does. Instead, they must be converted to Doom Graphics Format by selecting all imported entries, right-clicking on one and selecting Gfx → Convert to.... Then select "Doom Gfx (Paletted)", set both palettes to "Sonic Robo Blast 2" or "Existing/Global" and click "Convert All".
  • When importing a new sprite, SLADE doesn't automatically set image offsets like XWE. This can be done by right-clicking on the lump and selecting Gfx → Modify GFX Offsets. This menu allows to specify the type of sprite and automatically calculates the offsets based on that.
  • SLADE does not correctly view flats that are not between the F_START and F_END markers. This is intentional behavior to prevent non-flat lumps from being read as flats.


  • Some text lumps may be shown as "Unknown". To view their contents, right-click and select View As → Text or click the Edit as Text button above the lump display.
