Hatch monsters from eggs, make them fight to the death. If any survives, one of the labguys may be killed.

- Grab an egg and move it to one of the top grids.

- Monsters will fight to the death: their numbers decide who wins. If any survives, it's remaining life will be doubled!

- Monster steps one grid down. That also will give +1 to its life.

- If a monster steps off the grid, the autogun still could finish it, should there be ammo for it. The cooldown of the autogun decreases only, if two monsters kill each other. If there's no bullet in the autogun, the monster will eat one of lab guys (-1 life).

- Then choose the next egg to hatch.

- Grab a syringe to modify one or all eggs...

- Grab a pill to increase or decrease a monster's life points...
