Classic Campaign

The **Classic Campaign**, (formerly the *Main Campaign*), is the first and longest campaign in Micro Tanks. Levels within this campaign are called "Missions". This campaign features 99 regular missions, 4 boss missions, and serves as the gateway to 10 Secret Missions. Its Campaign Colour is red.

In the menu, once "Classic Campaign" is selected, there is an option to start the campaign at Mission 1, or select one of the campaign's seven checkpoints. Additionally, a "Beginner Mode" button starts the player in the Beginner Campaign.

## Progression

The Classic Campaign features 99 regular missions, 4 boss missions, and 10 Secret Missions. Checkpoints are unlocked every thirteen missions cleared.

### The First Quarter (Missions 1-25 + Boss 1)

The beginning of this campaign is easy and simple, featuring very few features, and introducing some of the more early-game tanks. This familiarises the player with the mechanics, such as blockers, firing, laying Mines, and some of the different possible enemy attacks and AI motifs. In the first ten levels, five types of enemy tank are introduced. Grey Tank, Celeste Tank, Yellow Tank, Teal Tank, and Purple Tank. In Mission 11, the Red Tank is introduced, and in Mission 13, the Lime Tank is introduced. Other elements such as Cracked Wooden Crates, Pits and Chests are introduced, too.

In the second half of the first quarter, more tanks are introduced, including Brown Tank, Lilac Tank, Azure Tank, and Rose Tank, but few additional elements are added. This first quarter culminates in Mission Royale, where the player must fight the Royal Tank.

### The Second Quarter (Missions 26-50 + Boss 2)

Starting at Mission 26, there is a marked increase in difficulty upon entering the second quarter. Levels with randomised tanks become more common. Cyan Tanks are introduced, and eventually more elements such as TNT Crates and Sandbags. A bit later on, Maroon Tanks are introduced. The forties are where the game's difficulty kicks up another notch. Towards the end of this quarter, the Green Tank and thus gas clouds are introduced. Nitro Crates and Paper Crates are also introduced. This is a perfect segue into the second boss fight, Mission Fumos, where the player fights the Cream Tank in a gas chamber level (the only level of its kind in the Classic Campaign).

### The Third Quarter (Missions 51-75 + Boss 3)

For the first 10 or so levels of this quarter, the difficulty doesn't really increase. This quarter starts to introduce some Assistants, starting with the Jammer. The Orange Tank is introduced. Upon reaching the 60s, the difficulty starts to increase again, and end-game tanks are now being introduced. Notably, the Olive Tank. In addition, C-4 Crates and Mahogany Crates are introduced. Upon reaching Mission 70, the Drone is introduced, marking a rather stark difficulty increase due to the number of enemies collecting power-ups. In the final level before the boss stage, the infamous Navy Tank is introduced. The boss fight is Mission Incendium, in which the player must fight the Scarlet Tank (the fire boss).

### The Fourth Quarter (Missions 76-99 + Boss 4)

Entering the fourth quarter, the difficulty starts to rise to insane levels. Upon reaching mission 80, the game is now extremely difficult. The Pink Tank becomes the final tank introduced in this Campaign, and the only new tank in this quarter. The Commander is introduced as the final new feature in the campaign. The 90s are all extremely difficult levels, almost impossible to beat deathless. Mission 99 sees the player face off all 18 tank types that were introduced throughout this campaign.

After Mission 99, the player is taken to a corridor that reads "GOOD LUCK" and an arrow pointing right made of Cracked Wooden Crates. Going all the way to the right triggers Mission Spectra, where the player must fight the final boss, the Rainbow Tank. This boss fight is extremely difficult.

### Ending

Once the Rainbow Tank has been beaten, the tank drops a key, which unlocks three Locked Crates on the right hand side of the level's outer perimeter. This is the first and only appearance of these crates in the Classic Campaign, although they are common in the Adventure Campaign. Going through the newly unlocked crates takes the player to the Treasure Vault, where there is a large abundance of Medals and Gems. It is implied that this whole time, the player was fighting to claim this treasure vault and steal all the treasure within.

## Beginner Campaign

As previously mentioned, the Beginner Campaign can be selected as a sub-campaign of the Classic Campaign. The Campaign colour for this campaign is white. This campaign features 20 missions, no bosses, and no secret missions. After mission 20, the game simply ends, along with a message in the Game Over screen stating "Congratulations, Cadet! You have cleared boot camp!"

The Beginner Campaign is supposed to be a much easier and accessible version of the Classic Campaign for beginners to practice. Each of the missions (except 20) are essentially repeats of their Classic Campaign counterparts. This campaign is almost identical to the first 20 missions of the Classic Campaign, but there are a few changes. Some of these changes include:

* Almost all tanks in the missions have been reduced to an easier tank than their Classic Campaign counterpart.
* The White Tank, the weakest tank in the game, is exclusive to this campaign.
* Some of the levels have fewer tanks than their Classic Campaign counterpart.
* Any secret areas or secret missions have been removed.
* Streakers cannot spawn in this campaign.
* All missions are fixed, even if their Classic Campaign counterpart had randomised tanks.
* Entry Level Discharge is the highest possible Discharge Status, even if you were to exploit mission resuming to get over 100 tanks.
* Mission 20 is an entirely new mission, which is similar to Mission 50.
* Tank introductions have been delayed to a later level than their Classic Campaign counterpart (e.g., Yellow Tanks first appear in Mission 7, instead of Mission 4).
* Medallions present in levels have been removed.
