The '''Multiple Tank Glitch''', also known as '''Multi Tank Bug''', is a special case of the [[Multiple Monster Glitch]] in which a tank is added to the monster list multiple times. | |||
For other monsters that are added to the monster list multiple times, the square simply spawns more the number of monsters equal to the number of instances in the monster list. This is not true of tanks, which only spawn once no matter how many times it is added to the monster list—except in a few special circumstances. These special cases can achieve very bizarre effects in a level designed with this glitch. | |||
This glitch occurs only in [[Microsoft's version of Chip's Challenge]]; it is not emulated by [[Tile World]] and does not exist in other [[ruleset]]s. | |||

If the tank has a sliding tile buried underneath it, then a curious effect will be observed if the tank slides on its first move. After the tank leaves the sliding tile, the tile buried underneath the tank will follow the tank and possibly morph itself into a different tile in the process. The exact tile that it morphs into is determined by an algorithm in Chip's Challenge, which is described in more detail in a later section. | |||
For example, consider the starting configuration below, where the tank appears twice in the monster list: | For example, consider the starting configuration below, where the tank appears twice in the monster list: | ||

Recall that there are four copies of each monster in the tile set, one for each direction. This is important to distinguish the direction in which a monster such as a [[glider]] is moving. In order to determine which index tile to choose, Chip's Challenge groups all the monster tiles into sets of 4 consecutive tiles. Within each group, the order of tiles in the set is north, west, south, east. In addition, the first tile in each group has an index that is a multiple of 4. | |||
In this glitch, tiles that are not normally monsters are also grouped as such since they behave as monsters for one turn. In the first example, the tiles [[Clone block|Clone block S]], [[Clone block|Clone block E]], [[Force floor|Force floor N]], [[Force floor|Force floor E]] are grouped together as one monster unit (although in reality, this grouping does not make any sense since these are not monsters). Note that Force floor E is designated as the "east" tile in this group, since it is the last tile in the group. This is why the east force floor happens to remain unchanged while it slides east. | |||
[[ | In the second example, the west force floor is the first tile in the group [[Force floor|Force floor W]], [[Exit]], [[Blue lock]], [[Red lock]]. As [[Red lock]] is the tile that is designated "east" in this group, this is what the west force floor turns into as it slides east. By extension, one can expect that if the second example were flipped so that the west force floor now slides west, it will turn into an exit (which is the "west" tile of its group), and this is indeed what happens. | ||
