Star Wars Jedi Knight: Jedi Academy
Developers: Raven Software,
Vicarious Visions (Xbox)
A spin-off of Star Wars Jedi Knight II: Jedi Outcast where you play as Kyle Katarn's Padawan, Jaden. This game features the ability to create a custom character and a custom lightsaber.
There are a lot of other leftovers from Jedi Outcast, including items and NPCs.
Most of these weapons are used by NPCs or mounted on vehicles, but they can't be normally obtained by the player making them go unused. They can all be obtained through the console command "give [Weapon Name]".
Stun Baton (weapon_stun_baton)
A leftover from Jedi Outcast. It is fully functional and can be accessed through the Inventory.
Bryar Pistol (weapon_bryar_pistol)
Kyle Katarn's blaster pistol from Jedi Outcast. Kyle can be seen using it on the Byss level. It does the exact same thing as the DL-44 Heavy Blaster Pistol.
Tusken Cycler Rifle (weapon_tusken_rifle)
The rifle used by the Tusken Raiders. It is sightly buggy and has no first person viewmodel.
Gaffi Stick (weapon_tusken_staff)
The staff used by the Tusken Raiders. It does no damage.
Scepter of Ragnos (weapon_scepter)
The scepter that Tavion uses to resurrect Ragnos. It's buggy, but it works. It is possible that the player would obtain it if [s]he turned to the dark side.
E-Web Blaster Gun (weapon_emplaced_gun)
A portable version of the E-Web Blaster Turrets. It has no model.
TIE Fighter Cannon (weapon_tie_fighter)
This is the cannon from the Byss mission that is used to shoot down the TIE fighters. It's also a leftover from a similar cannon in Jedi Knight 2.
Noghri Stick (weapon_noghri_stick)
The Noghri's poision spray stick can be obtained. Unfortunately it just crashes the game when fired.
Jawa's Ionization Blaster (weapon_jawa)
There is a leftover reference to the Jawas' ionization blaster in the files. Nothing remains of the weapon's coding.
These can all be accessed with the command "npc spawn vehicle [vehicle name]".
Z-95 Headhunter (z-95) Jaden's ship. It is very glitchy when it crashes into something.
X-wing (x-wing) Wedge's X-wing fighter. It is also extremely buggy.
TIE Fighter (tie-fighter) A TIE fighter. It is also very buggy.
TIE Bomber (tie-bomber) Like the others, it's very buggy.
TIE Bomber 2 (tie-bomber2) An alternate version of the TIE Bomber. It's pretty much the same thing.
Lambda Class Imperial Shuttle (lambdashuttle) Same as all the others.
Rideable Rancor (rancor_vehicle) A rideable version of the rancor. It is functional and the player can use their lightsaber and the blaster rifle on it.
Unused Force Power
If you cheat and get Mind Trick level 4, you can use this power to take control of NPCs. The only problem is that any weapons that aren't lightsabers fire very fast.
You can obtain Tavion's sword by typing in the command "saber sith_sword". It's buggy and has very high damage stats. It is possible that the player would get it along with the Scepter if [s]he turned to the dark side.
On the Tatooine spaceport level there is a locked door up some stairs. If you noclip behind it you will find 3 unused rooms including one with an unused Chewbacca NPC.
An obviously temporary texture. The name suggests it was an inventory icon for the ammo dispenser.
Another obviously temporary texture. The name suggests it was an inventory icon for a health dispenser, but there is no health dispenser in the game.
