Sandbag

**Sandbags** are a blocker within Micro Tanks. The blocker appears as a pile of sandbags. Unlike other blockers, these are often resized, and are usually not 64x64.

## Properties

Sandbags act as walls, and are solid objects to any tank or non-flighted entity that collides with them. However, notably, this block "absorbs" things that come into contact. When Bullets hit them, they are destroyed, even if they had not yet reached their ricochet limit. For instance, if the player bullet, which has one ricochet, hits a Sandbag when it has not yet ricocheted, it will be destroyed regardless. Sandbags are also able to occlude explosions. Any explosion-sensitive entity such as a tank, bullet, or destructible crate will not be affected if there is a Sandbag between the object and the source of the explosion.

Sandbags are totally indestructible, resistant to all sorts of blast and explosion. However, airborne attacks such as gas clouds can float over them. Flighted enemies such as the Drone and the Rainbow Tank can also fly over Sandbags.

In Mission 84, Sandbags appear to be in the walls, however, these sandbags do not collide with bullets at all, since this is how the secret area is accessed. In fact, these are fake sandbags. There are, however, invisible real sandbags in the metal crate part of the walls so that the explosions are still blocked.

### Sandbagged Metal Crates

In some missions, Metal Crates are "sandbagged". This is where a sandbag is embedded within walls created by metal crates. With this set-up, the wall allows bullets to ricochet, but blocks explosions from reaching the other side. This is usually used to stop the player easily blowing up stationary tanks on the other side of a wall.

## Trivia

* In the Classic Campaign, Sandbags appear in 27 normal missions, 2 boss missions, and 3 secret missions. That is a total of 32 missions out of 113. That means Sandbags appear in 28.3% of all missions in the Classic Campaign.
* Sandbags, unlike other blockers, are often seen in sizes different to the standard 64x64 model. Mission 87 has the largest single sandbag by a long shot.
	+ The extremely large Sandbag in Mission 87 is in fact fake. The area is actually filled with a lot of invisible smaller sandbags. This is because the collision with the extremely large Sandbag would be highly inaccurate and incorrect at such a scale.
* Cinnabar raged on Discord about how long it took to code explosion occlusion for every single bullet type and Mine type from every single possible explosive source. It took upwards of 12 hours, and had to be done over several days to not go insane.
* Mission Fumos is the first mission in the game to have the embedded sandbags within walls. However, the first mission Cinnabar designed with this feature was Mission 55, which was actually created *before* Mission Fumos.
* They do not appear until Mission 36 of the Classic Campaign, however, they appear in Secret Mission 20. This is considered an "unofficial introduction", since Secret Mission 20 will likely not be discovered until after a person has reached Mission 36.
