Editing Blam engine

{{Status|RealWorld}}

Nonetheless, many improvements were made over the ''Myth'' engine. Circa [[1999]], Blam supported features such as [[Wikipedia:Volumetric lighting|volumetric lighting]], per-pixel [[Wikipedia:Reflection (computer graphics)|reflections]] and [[Wikipedia:Texture mapping#Multitexturing|multitexturing]]. All of these features would eventually make it into the game's [[Xbox]] release in [[2001]]. At that time, the engine also supported a [[Wikipedia:Destructible environment|deformable terrain]] system, where explosions and orbital strikes would create permanent craters in the landscape.{{Ref/Reuse|JJInt99}} However, this feature was ultimately cut.

===Future games===

Each successive ''Halo'' game developed by Bungie was built upon the Blam engine, and it was significantly evolved with each successive game.

The Slipspace Engine is a heavily revamped and modernised game engine developed by [[343 Industries]], which is derived from Blam. While containing significant amounts of new and overhauled code, the engine is ultimately based upon the version of Blam used in ''[[Halo 5: Guardians]]'' and still retains remnants of this engine.{{Ref/YouTube|8qqGrIFlgXQ|Halopedia Archive|343 Social Stream - Happy Halodays (19 December 2018)|Time=1389|Detail=23:09}} ''[[Halo Infinite]]'' is the first game to utilize the Slipspace Engine, and it will presumably succeed the Blam engine as the engine of choice for future ''Halo'' titles.{{Ref/Site|Id=SlipspaceOurJourneyBegins|URL=https://www.halowaypoint.com/en-us/news/our-journey-begins|Site=Halo Waypoint|Page=Our Journey Begins|D=22|M=9|Y=2021}}

One of the key design goals of the ''Anniversary'' remasters of ''Halo: CE'' and ''[[Halo 2]]'' was to leave the titles' original gameplay completely untouched, so that the games would play exactly as they originally did. As a result, both ''[[Halo: Combat Evolved Anniversary]]'' and ''[[Halo 2: Anniversary]]'' use their respective game's original engine. However, in order to produce the remastered anniversary graphics, developer [[Saber Interactive]] needed a significantly more modern [[Wikipedia:Rendering (computer graphics)|rendering engine]]. Thus, for each of the games, they retrofitted their own internally-developed engine, the Saber3D engine, onto the original engine to facilitate the remastered graphics, while preserving the original Blam engine's gameplay logic so that the games play exactly as they originally did. This has been compared to essentially running two game engines at once, within the same game. This unique design also allowed for the ability for the player to switch between the two graphical modes at any time within the gameplay - a tool originally developed to allow developers on ''Anniversary'' remasters to rapidly compare their new artwork with the original game. However, the tool was turned into an official feature.{{Citation needed}}

These constraints were not compatible with ''Destiny'' in a number of ways: it was a multi-platform game targeting release on a multitude of consoles, all of its target platforms contained [[Wikipedia:Multi-core processor|multi-core processors]] which requires [[Wikipedia:Thread (computing)Single-threaded_vs_multithreaded_programs|multithreading]] to take full advantage of, and finally, ''Destiny'' would feature many sizable content updates after launch, which Blam did not support.  However, Bungie still wanted to preserve large portions of the Blam engine, notably the gameplay framework and networking code, and so couldn't build a new engine or switch to a third-party one.{{Ref/Reuse|TigerEngine}}

Multiple games have also been prototyped using the Blam engine:
