Halo Editing Kit

The Halo Editing Kit, also known as the HEK, was released by Gearbox Software along with the Custom Edition. It includes basic tags for bitmaps, vehicles, weapons, bipeds, and other necessary elements of a Halo map. The kit comes with three programs which assisted in mapping.

• The first is tool. Tool is both the backbone and the pain of CE. Although it works to do everything from bitmap creation to the final map-building, its old-style command prompt methods have driven at least a few mappers insane.
• The second program is guerilla. Labeled with a gorilla (pun intended), this program opens the tags themselves for editing. Guerilla is the only program that can change the game tags.
• The third program is sapien. Following the primate theme, sapien opens scenario tags (the early map files) and creates a visual representation of the final map. Mappers can insert vehicles and weapons, place spawn points, and make camera points for cutscenes. Everything that can be positioned in the map physically is done with Sapien.

The HEK also includes the HEK tutorial, which is a step-by-step walkthrough of the making of the tutorial map. The tags that come with the kit are almost singularly made for this small map, but include the bitmaps from every Halo 1 level, both campaign and multiplayer. The combination of the tags, programs, and tutorial gives players a glimpse into the possibilities of the Custom Edition.

Because the HEK is only a basic group of files, CE mappers had to experiment and share their discoveries on the workings of the game. Over time they realized that most of the game tags were excluded from the HEK. This prevented a huge amount of creativity that could be harnessed in new maps. People began tinkering with the HEK programs. Kornman produced a new version of Guerilla called Kornman00 which unlocked all the grayed-out areas in the program. This new program allows for editing of terrain bitmaps, AI modifications, and many other previously impossible actions. He also created a user-friendly version of tool called Tool++ and an unlocked version of Sapien called a_hobo.

The largest breakthrough of tag availability was Steelix B's HEK+, which allows anyone to enter any map, CE or otherwise, and extrace any tag they want. Along with a few others, Steelix decompiled the entire Halo PC game into its basic parts. CE mappers now are able to do nearly anything they want. This includes programmed AI in maps, user-flyable pelicans and longswords, and the easy ability to create campaign-multiplayer conversions. Already the campaign is being rereleased with different tags, including some H2 recreated weapons.

Now, many advancements have been made within the program, the maps, and even the mappers themselves. Expert scripters such as Kornmann, Rec0, Bitterbannana, and Tiamat have made various scripts to help boost the interest in the maps.
