Team Fortress 2/Unused Text

There's a good chunk of unused text in TF2. Some of it seems to be deliberately unused, to throw modders looking for hints towards the next update off the scent. Other parts are from failed design experiments.

TF2 MMO
This is a joke at the expense of people learning about the existence of Hats earlier than they were supposed to. // TF2 MMO "TF_MMO_LFG"				"Looking For Group" "TF_MMO_Quest1"				"You must kill %s1 %s2 to complete this quest." "TF_MMO_Monster1"			"Boars" "TF_MMO_Monster2"			"Rats" "TF_MMO_Monster3"			"Bats" "TF_MMO_Monster4"			"Wolves" "TF_MMO_Monster5"			"Spiders"

Dustbowl Text
These were presumably from Dustbowl being more like it's Team Fortress Classic counterpart. In the final game (as far as anything in TF2 can be declared final) Dustbowl uses standard control points without needing to hold a flag.

"Dustbowl_team1"			"Attackers" "Dustbowl_team2"			"Defenders" "Dustbowl_you_secure_one"		"You secured\nCommand Point ONE !!" "Dustbowl_you_secure_two"		"You secured\nCommand Point TWO !!"

Challenge Text
These are from the updated main menu's class stats boxout that's since been removed. "%challengeclass%" was replaced with the class in question's name. It'd randomize what gender it referenced the Pyro class as for added ambiguity-related comedy.

"ChallengeTitle"			"%challengeclass%" "ChallengeSubText"			"Why don't you give him a shot?" "ChallengeSubTextB"			"Why don't you give her a shot?" "ChallengeRecord"			"Beat this:" "ChallengeDetails"			"%s1 as a %s2"

Gadget Token Text
Added in the Australian Christmas update. When asked about it, Robin Walker described this as "some old prototype stuff we were messing around with, and stopped working on." This text has since been removed, as part of the September 16th, 2011 patch.

"CI_T_G" 				"Gadget Token" "TF_Unique_BleedingSocketItem" 		"Leakium" "TF_Unique_BulletResistItem" 		"Bulletproofium" "TF_Unique_FireResistItem" 		"Fireproofium" "TF_Unique_BlastResistItem" 		"Blastproofium" "TF_Unique_HealthRegenItem" 		"Firstaidium" "TF_Unique_SpeedBoostItem" 		"Sprintium" "TF_Unique_MetalRegenItem" 		"Harvestine" "TF_Unique_CloakRegenItem" 		"Invisine" "TF_Unique_CloakConsumeItem" 		"Longvisine" "TF_Unique_RepairRateItem" 		"Wrenchine" "TF_Unique_ConstructionRateItem" 	"Constructine"

Unused Item Quality String
A name string for the unused item quality "Completed" can be found in tf_english.txt. Oddly enough, name strings for the other unused item qualities (Customized, rarity2 and rarity3) are not listed.

"completed"				"Completed"

Unused Weapon Name Strings
The following name strings can be found in tf_english.txt, and reference unused weapons.

"TF_Weapon_Nailgun"			"Nail Gun" "TF_Weapon_Tranq"			"Tranquilizer Gun" "TF_Unique_Achievement_SniperRifle"	"Walkabout" // ADD THE "TF_Unique_Logo_Shield"			"Heraldic Targe" // ADD THE "TF_Weapon_Crowbar"			"Crowbar" "TF_Weapon_SuperSMG"			"Super SMG" "TF_Weapon_Flag"			"Flag"

As well, in game_sounds_weapons.txt, the Fire Axe has the heading BRANDING IRON, referring to the Pyro's original melee weapon, the Branding Iron, which has an untextured model in the game files.

Unused Weapon Attributes
Located in the game's .gcf are various unused weapon attributes, with varying degrees of functionality. While most of them are unused but completely uninteresting (+% less accurate/+% more ammo, etc.) there are several which indicate weapons which were removed altogether. Among the more interesting mechanics:
