DeVuego PT

To complete the levels of Kraal, you must kill all the larvae (small, oval insects without legs) and their mothers (large larvae with eggs embedded on their backs). If you kill the mothers first, one of the larvae will transform into a mother, generating another larva in the process, thus stabilizing the balance. So the larvae must be destroyed first. Furthermore, when a larva is hit, it becomes agitated and moves faster, so your attack must be quick and effective.

In the game, spiders appear that launch webs “energy drainers”, flies, the Eyes and Oktups (a large beast resembling an octopus) you don't need to kill them all to complete the level. However, the Oktup and the Mother, when killed, release four precious stones that can be exchanged for better weapons, extra energy or a view of a map of the current level (in which the Larvae and Mothers are represented by a flashing block, other aliens are represented by a block with a checkerboard pattern and walls by a block with a “solid fill”). The precious stones are exchanged at the exchange deposit, a light blue and red tube surrounding a green sphere.

There are also scattered throughout the wells, various transporters (the same tube as the exchange deposit but around a blue square) that teleport the vehicle to different parts of the well.

The alien counter shows the number of larvae and mothers remaining in the level.

In the following levels, there is the added difficulty of the large number of tubes and building structures that obstruct your view.
