The video game consists in defending the nucleus, while trying to avoid that the enemies destroy it, on the other hand, the enemies can also eliminate you. Therefore, the player must be aware of both the protection of the nucleus and his own life. The player will have the possibility of obtaining different abilities, but to obtain them he must leave the central zone where the nucleus is, forcing the player to leave him defenseless in search of new abilities to counteract waves of enemies.
