Fortress Forever is a Source mod inspired by the earlier versions of the Team Fortress series (Team Fortress Classic and QuakeWorld Team Fortress). Our all-volunteer team has created this mod entirely from scratch and continued to develop it for over 5 years now. It was originally released in September of 2007. Fortress Forever involves two or more teams, each with 9 available classes, competing in a variety of map-determined objectives (capture the flag, territorial control, invade and defend, etc). Each class has its own unique abilities and strengths that offer extremely varied playstyles. The gameplay ranges from fast-paced, competitive, and deep to absurd and chaotic.

  • Totally free; only requires a Steam account with Source SDK Base 2006 installed.
  • Fast paced, team- and class-based gameplay
  • Faithful to the spirit of Team Fortress Classic (TFC) and QuakeWorld Team Fortress (QWTF), meaning Fortress Forever includes offhand grenades, bunnyhopping, etc
  • 10 Classes (9 + Civilian)
  • Training level and in-game hints
  • Extensive map scripting/customization using Lua

Misc Resources

Abbreviated Changelog (v2.46 to v2.5.0)


  • Added different kill icons for unbounced rails, single bounced rails, and double bounced rails
  • Added airshot detection
    • Airshots show in the console like so: player killed player with weapon (airshot)
    • Airshots are logged to file like so: "player" killed "player" with "weapon" (modifier "airshot")
      • The (modifier "") string only gets added if there actually was an airshot, otherwise the entire parenthetical is absent from the line
  • Added sparks/dust to the feet of rampsliders (cl_rampslidefx cvar for toggling the effects on/off, and cl_rampslidefx_* cvars for controlling how it looks/behaves)
  • Added team-colored trail to flags
  • Allowed bounced rails to collide with their shooter
  • Added hud_weaponselect cvar (briefly shows the weapon select menu whenever switching weapons when hud_fastswitch is enabled; defaulted to enabled)


  • Lowered the hard cap from 180% to 171%
  • Flag touch bounds have been decreased somewhat significantly: touch height is now ~65% of flag height, and touch width is now ~100% of flag width (flag touch bounds used to be larger than the flag itself in both dimensions)
  • Added a middle bhop cap - when you are over it, reduce speed by more. Currently set to 1.55 speed (620 for scout) and it has a lower pcfactor (0.3 rather than 0.65). This means downtrimping is good for one jump and reduces successive conc skim jumps without reducing the hard cap too much
  • Made HH explosive grenades (frag/mirv) work like they do in TFC (HHing a gren now simply adds 1000 speed in the direction that you're currently moving (or 950 speed straight up if you're not moving at all)
  • Capped jump pad + conc horiz and vert speed separately
  • Set jump pad horiz boost to 768 (was 1024 in 2.46)


  • Removed the single shotgun from the hwguy, medic, and pyro (see #82)
  • Removed nailgun from sniper
  • Made the sniper rifle use nails to avoid shared ammo between sniper rifle/autorifle


  • Slimmed down the number of maps included with FF
  • Improved base_shutdown.lua
    • Added built-in support for trigger-based buttons (blue_security_trigger/red_security_trigger)
    • Added built-in support for Lua-defined security shutdown length (SECURITY_LENGTH)
    • Added built-in support for turning on/off lights, brushes, trigger_ff_clips, and trigger_hurts
    • Added some helpful team-oriented trigger definitions in base_teamplay.lua
  • Added a timer on the HUD that reflects how long security is down for on all security maps
  • Reverted all IvD maps that used the time-limited-round-based system to the default IvD system (only switch teams after all caps have been captured)
  • Removed the objective icon on the flag for defenders in IvD/AvD maps (it always points to the cap point that needs to be defended instead)
  • Changed the team names in ff_dm to something more appropriate
  • Removed the map guide menu as it has never been utilized
  • Allowed the speedometer to show while spectating someone


  • Added Spanish translation by VMX and Firefox11
  • Added (incomplete) Russian localization by Gordon
  • Added Portuguese (BR) translation by Gemini Saga
  • Defaulted hud_fastswitch to 1
  • Made 0 prematch the default when using ff_restartround without a parameter (ff_setprematch is better for cases where you just want to add prematch)
  • Added hud_fastswitch and hud_weaponselect to the Fortress Options "HUD" section
  • Reverted back to the 2.4 menu background because it was pretty cool
  • Removed the map guide menu and make the Flythrough button go directly to the flythrough
  • Improved HUD font: add Latin-1 Supplement and other missing chars (adds things like custom accented chars, #, &, $, ~, etc)
  • Optimised Lua HUD network messages (send a number ID over the network rather than a string)


  • Fixed spectators not getting their kills/deaths/fortpoints reset on restart round
  • Fixed getting a frag added when using the 'spectate' console command (it used to be to compensate for the -1 frag from suiciding)
  • Fixed grenades disappearing after falling too far
  • Fixed flags getting stuck in ceilings
  • Fixed ff_training not showing map loading info when launched from the main menu
  • Fixed ff_restartround resetting twice when called with 0 prematch time
  • Fixed unicode character support in VGUI/HUD elements
  • Fixed materials/ff/ff08_sign_up_green material using the yellow texture instead of the green one
  • Fixed the glass material in ff_dm
  • Fixed conc speed being limited for too long after using a jump pad (#80)
  • Fixed Lua HUD timers' seconds getting truncated in the wrong direction when counting down

There's a little clique that plays now and again, probably EST, which makes it fun and not fun depending upon, I guess, their "mood". Even then not very many players, maybe 4 or 5 in the core clique then 1 or 2 others maybe...

Still the mod itself is fantastic as it's what TF2 SHOULD have been rather than the dumbed down crap that it turned out to be. I'd've even preferred a source port of TFC straight OVER TF2, which I bought, but haven't played in years as it's nowhere close to as much fun as TFC was an FF was in the early days.

IF they can get on steam as regular updateable option, I'd expect to see more players given the hopefully expanded exposure, but right now FF is just rotting in virtual anonymity.

I'm getting what seems to be a phantom upgrade from Desura for this now as well. Indicates upgrade available then claims no upgrade when going through the "upgrade" process, but OTOH Desura is super flakey at best.

ff is way unballanced... THAT is why no one plays, also maybe you should try out tf2, it HAS been years since you played it, and i'm sure you'll agree that it's not as dumbed down as you'd like to think. just as fun if not better than tfc. (i'm sure that as i once was, you're just being biased cause of the cartoon style tf2 has, trust me, everyone has this bias at first)

agree with that ff is unbalanced, like the scout his nailgun can easely destroy a sentry and the sentry deals to less damage while in tf2 this isnt the case

This mod makes me feel as if I was playing Team Fortress Classic!

Jun 6 2011 by nikorasu_san

Lowest Rated (8 agree) 5/10

Instead of taking team fortress classic and improving it in a new original way without it being a copy paste of TF2... instead they decided to remake team fortress classic... exploits and all. Scout still feels weak, medic is still unusually powerful. The maps are rather underwhelming.. Bunnyhopping, all I want is a option to disable it. Any server that has disabled bunnyhopping would automatically have a tag that says "bhop off" so it wouldn't hurt anyone. Quake was designed for strafe jumping…
