{{Titanfall|4}} is a multiplayer first-person shooter video game, developed by Respawn Entertainment and published by Electronic Arts. It runs on a heavily modified version of the {{src|4}} Engine based off {{portal2branch|4}}{{ref|1}}, with a custom version of BSP, a custom version of the VPK package format, and an improved rendering engine. The sequels and spinoffs, {{titanfall2|4}} and {{apex|4}}, both use this same engine, but with improvements.

Respawn chose to use the {{src|4}} 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 {{Idtech3|1|nt=0}} (also known as {{Idtech3|1}}) used in [[WP:Call of Duty|Call of Duty series]] (called [[WP:IW_(game_engine)|IW engine]]), and because of Source's ability to maintain a constant 60FPS on the {{360|2}} and {{ps3|2}}.

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 [https://en.wikipedia.org/wiki/Denial-of-service_attack 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 ==
; [https://en.wikipedia.org/wiki/Direct3D#Direct3D_11 Direct3D 11] renderer
: First Source engine game to render on Direct3D 11.
; [[Anti-aliasing#TAA|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. Through it's main drawbacks is that it can cause ghosting and blurriness (basically creating motion blur) to the image, especially on lower framerate ([https://www.youtube.com/watch?v=GJ0eFYJYkkw 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 lighting|Deferred shading]]
: Allow many lights to be rendered on scene with little performance impact.
; 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|HDR Rendering]]
: Improves the HDR (bloom) lighting.{{clarify}}
; Customized version of [[BSP]] and [[VPK]]
: Titanfall uses BSP version 29, with the BSP headers using {{code|rBSP}} (Respawn BSP) instead of {{code|VBSP}} as identifier.
; Modern and next-gen console support ({{PS4|2}}, {{PS5|2}}, {{nsw|2}}, {{Xboxone|2}} and {{XboxXS|2}})
: Of little use to modders, needless to say!

== Limitations ==
{{ModernImportant|Servers are down or frequently DDoSed since 2021 according to several reviews on Steam.}}
{{warning|The mouse sensitivity for this game is tied to the framerate.}}
