Titanfall

is a multiplayer first-person shooter video game, developed by Respawn Entertainment and published by Electronic Arts. On PC, the game was originally released on Origin (now EA App), but later released on . 
Titanfall runs on a heavily modified version of the (), based off , with modifications such as heavily modified BSP format, VPK package format, and an improved rendering engine. The sequels and spinoffs, and , both use this same engine, but more heavily modified and improvements.
Respawn chose to use the engine for Titanfall and subsequent games as the co-founders and former Infinity Ward staff (who joined Respawn) are previously familiar with the heavily modified (also known as ) used in Call of Duty series (called IW engine). Both IW engine and Source have codes dating back to Quake. Respawn also chose Source because performs well on .
Titanfall restricts typical Source engine features such as the developer console and server browser, but these can be re-enabled with offline mods.
As of 2021, Titanfall is no longer available and has been delisted from Steam as the game servers has suffered from DDoS attack and the game was left unpatched with many known security vulnerabilities. The game received review bombing on Steam shortly before and after it got delisted.
== Features ==
=== Renderer ===
; Direct3D 11 renderer
: First Source engine game to render on Direct3D 11.
; Cascaded Shadow Maps
: Titanfall uses CSM, which cast very detailed shadows from the skybox.
; TXAA anti-aliasing
: TAA (aswell as TXAA, TSSAA or TSAA and other variant of TAA) is a new method of anti-aliasing which was common in later games since 2010s, as most games are transitioning from forward rendering to deferred rendering which allows many lights to be rendered with little performance impact. TAA is a spatial anti-aliasing technique that works by combines information from past frames and the current frame (while simultaneously jittering between both frames) to smooth the current frame, this results in significantly cheap performance impact comparing to other methods like MSAA, and works better with deferred rendering. Through it's main drawbacks is that it can cause ghosting and blurriness (basically creating motion blur with ghosting trails) to the image, especially on lower framerate (Example).
: TXAA requires MSAA to function, unlike newer implementation of TAA in later Titanfall games.
; 64-bit support
: First Source game to run on 64-bit natively, which improves performance and allow the engine to access more than 4GB of RAM. 32-bit are not supported.
; Deferred shading
: Allow many lights to be rendered on scene with little performance impact.
=== Network ===
; New netcode
:
; Audio system improvements
: Speex audio codec
: Titanfall uses Wwise sound system.
; Texture streaming
: Reduce system RAM and graphics card VRAM by streaming textures.
; Better HDR Rendering
: Improves the HDR (bloom) lighting.
; Customized version of BSP and VPK
: Titanfall uses BSP version 29, with the BSP headers using (Respawn BSP) instead of as identifier. Titanfall also use custom version of VPK file format.
; Next gen console support ()
: Titanfall runs on 8th genXbox One, at 60FPS. Not useful to modders however.
