BattleTanx
Developer: 3DO Company Publisher: 3DO Company Platform: Nintendo 64 Released in US: December 31, 1998 This game has unused areas. This game has unused code. This game has unused items. This game has unused music. This game has unused text. This game has a hidden level select.

Earth Needs Women! ...with tanks.

To do: Document the game breaking bug of using the infinite health cheat in a bonus level.

Unused Cheats

Inside the cheats section of the game, there is four hidden cheats, only two of which have proper cheat names. They can be inputted with some GameShark trickery. The two cheat strings that can be inputted are "??????????" and "DUMMYHAHA". However, there is no letters "A", "?" and "U" in the input code screen. There are codes to force the game to display the letters (found in each code's own section).

??????????

This rewards you with the cheat "VALID LEVEL CODE" when correctly inputting it and will enable level select for campaign mode. Unfortunately, you cannot use any of the maps in the level select that are not designed for campaign mode (not without more GameShark codes at least.)

Replaces "C" with "?" in INPUT CODE screen
80135681 003F

This GameShark code replaces the letter "C" with "?". The spot where "C" once was will be blank, but the game will still recognize it as "?". Input ten question marks to enable this cheat. The "?" will be blank when inputting them as well, but ten is the maximum amount of letters it will accept anyway.

The levels, MPWharf, MPMissile, Spare 1, Spare 2, Spare 3 and Spare 4 do not work.

DUMMYHAHA

When inputting this code you will be rewarded with the cheat, "TOD CHEAT", granting you invincibility, unlimited ammo, automatic radar at the start of each match, and level select (for campaign mode). Neat!

You can replace "B" and "Z" with "A" and "U" using the following GameShark code, allowing you to input the code DUMMYHAHA:

Unreferenced Cheats

These two cheats have no proper name/input, so they can only be enabled through GameShark codes.

One cheat disables the HUD and you can no longer properly see the pause menu. It does not refer to any cheat text at all. Enable this with the following GameShark code:

80135770 0001

The other cheat allows you to always have radar at the start of each match. It is also enabled when you use the DUMMYHAHA cheat. It could have been its own cheat at one point. Enable this with the following GameShark code:

80135761 0001

Unused Levels

When you spawn in most of these unused levels you will get stuck inside a clump of tanks. Apply the following GameShark code to disable collisions for Player 1 to properly explore these maps:

Disable Collisions
812D858A 0000

To enter one of these levels, apply its corresponding GameShark code then enter a single player or multiplayer map that is not under "Campaign" to play them.

Intro Level

This level has a couple of hidden pickups in it. Use the code below to enter the level:

81135676 0000

• 
• 

  Has two swarmer pickups inside a "BATTLETANX" wall.

• 

  Behind these walls lay four Nuke pickups.

• 

  Four hidden Nuke pickups.

Crimson Gate (Multiplayer Version)

It appears Crimson Gate was once going to be a multiplayer map, even having proper spawn points for each team. The map is quite cramped however, likely contributing to it being cut for multiplayer. You can enter this level by activating the following GameShark code:

Test 2

A test level resembling one of the unplayable cutscene "levels". You can enter it by activating the following GameShark code:

81135676 0019

• 
• 

  Normally you cannot see these group of mines in the cutscene.

• 

  Another normally unseen group of mines.

Test 3

Appears to be a half finished version of Lake Shore Drive. You can enter this level by activating the following GameShark code:

81135676 001A

• 

  Proper spawn points for Player 1's team. Also has an indestructible Queenlord base.

• 

  All pickups are health and ammo on this map.

Unused Weapons

Four unused weapons can be found in the game's code. Only two of them function properly, the "Laser Nuke" (actually used by the AI in the intro cinematic, but unavailable to any players) and "SMOKESCREEN" (creates a cloud of smoke, as the name implies). They can be put back in your inventory. They can be put into your inventory with the following code (must have at least one weapon already in your inventory):

Put "Lazer Nuke" and "SMOKESCREEN" in your inventory
812D8614 0064
812D861C 0064

The other two unused weapons, while non-functional, can still be put in your inventory with this code:

Put unknown weapons in inventory
812D8610 0064
812D8612 0064

Unused Pickups

Two unused pickups, "FLAMER" (no function) and "SMOKESCREEN" (creates a smokescreen, similar to the weapon variant), can be found within the game's code. "FLAMER" most likely appeared later in BattleTanx: Global Assault. It's unclear what "SMOKESCREEN" would have been used for.

You can apply the following code to see them in game, though they will only work on the Intro Level. This code replaces the four nukes found in that map.

Unused Song

A rather plain song not used anywhere in the game can be found left in the code.

Unused Main Menu Remnants

Function 0x8007c864 appears to be an unused main menu. There is no longer any code in the game that makes use of this function. The below text would have been used by this function.

"Level %s\r\n"
"Campaign\r\n"
"MultiPlayer\r\n"
"\r\nTeam %d\r\n"
"Aggressiveness = %f\r\n"
"Intelligence = %f\r\n"
"Offense = %f\r\n"
"Defense = %f\r\n"
"ai speed factor = %f\r\n"
"ai fire rate = %f\r\n"
"goliath fire rate on rails = %f\r\n"
"goliath fire rate off rails = %f\r\n"
"goliath speed factor on rails = %f\r\n"
"Gun Resurrection = %f\r\n"
"Gun %d Fire Rate = %d\r\n"
"Gun %d Damage = %d\r\n"
