Treasure Vault

The **Treasure Vault** is a room that is accessed following beating the final boss stage of the Classic Campaign, Mission Spectra. The room features no enemies, and serves as the reward for beating the final boss, and is the ending to the Classic Campaign. As it turns out, the hidden objective of the game from the beginning was to take this Treasure Vault, and the treasure within has been the player's motivation for killing all these tanks. It can even be implied that all the tanks were merely guards to this vault.

## Access

The Treasure Vault is accessed once the final boss, the Rainbow Tank, is beaten. Mission Spectra features three Locked Crates on the right hand side of the outer perimeter. The Rainbow Tank, upon death, drops the key. When the player picks up the key, the Locked Crates are opened, and the player can then move through the gap on the outer perimeter, and be taken straight to the Treasure Vault.

The player leaves the Treasure Vault, therefore ending the game, by going through a similar three-block gap on the right hand side of the outer perimeter of the vault.

## Features

### General

The Treasure Vault is a room that is slightly larger than the standard arena, by virtue of the fact the bottom dashboard is smaller, since it does not show the power-ups. The room has a rich gold filter, and the floor is a taupe colour. The outer perimeter of the map features gold-tinted metal crates. Across the floor, there are large pools of gold, and lots of sparkles throughout the room.

No music is played in the Treasure Room. There are no enemies, but you can still die if you blow yourself up. Should this happen, you will respawn where you died, like in a boss stage.

### Treasure

The room features an abundance of Medallions and Gems scattered all throughout it. In fact, the Treasure Vault is by far the best way to get a lot of Gems. The medallions and gems are randomly generated when the player enters the room.

The amount of gems and medallions is tied to how many missions the player completed. For instance, starting the game at Mission 76 and beating the final boss yields less treasure than starting the game at Mission 26 and beating it. The maximal treasure is obtained when the game is started from the beginning and beaten in one run.

The specifics of treasure generation is detailed below:

* **Gems** generate at a rate of 2.5 per mission cleared, rounding down. This means that beating the full game from start to end, 103 missions, yields **257** gems, enough to buy the Rainbow Skin.
* **Silver Medallions** generate at a rate of 1 every 5 missions cleared.
* **Gold Medallions** generate at a rate of 1 every 10 missions cleared.
* **Royal Medallions** generate at a rate of 1 every 20 missions cleared.

### Unique Medallions

The Treasure Vault features two unique medallions not found anywhere else in the game. Regardless of how many missions you clear, when entering the Treasure Vault, between two and four **Bronze Medallions** generate. These are worth 5 medals, and are not found anywhere else in the game.

If you beat the Classic Campaign from start to finish, one **Diamond Medallion** will generate. This one-of-a-kind medallion is cyan in colour and sparkles, and is worth 100 medals.

## Trivia

* Getting a Game Over in the Treasure Vault by blowing yourself up and losing all your lives actually still takes you to the "Game Won" version of the Game Over screen, as if you had exited the Treasure Vault through the right-hand-side.
* The existence of the Treasure Vault is hinted at in one of the Splash Texts, by saying "But what are they even fighting over?" It is implied here that there is a greater purpose to killing these tanks. You are in fact fighting to take this treasure vault.
* Originally, the Treasure Vault was to be the only source of Gems.
