Alien Invasion
While questing, Alien Invasions are randomly triggered. In order to take part in the event, Psi Energy must be used. Psi-Energy can be obtained by mixing Quest Energy, Attack Energy, and Defense Energy*. This allows users who progress through the game by solely questing or those who use only take part in battles to effectively use the energy not being consumed. *Note: due to updates, Psi-Energy now regenerates like all the other types of energy.
Evolution
If Psi-Energy is fully charged, players can immediately face the Alien Invasion. When the Alien attacks, the Defense Squad tanks the damage, and immediately after, the Attack Squad delivers an attack. The battle progresses in this fashion until the Alien threat is defeated. But just because the battle is over does not mean you should let your guard down. At higher levels, Aliens can evolve (level up) and return for additional rounds.
Alliance
By having more allies, Alien Invasions become more frequent and easier to defeat. Alien Invasions can be done in co-op with allies. If a friend triggers an Alien Invasion, alliance members will be notified to join. The player who deals the most damage, the one who delivers the final blow, and the strike leader will all receive bonus rewards.

Healing abilities - The difference between flat healing and percentage is that flat has a certain amount of health that it gives back to the alien and the amount is generally not too high so it's easy to deal consistent damage to them. The percentage is much harder since those aliens have a very high base maximum health and they heal for more due to that high amount. Most players, even high end ones, can't deal enough when a max Kractus heals for 2 million every other turn and those players only deal 100k to 200k damage a turn. The developers introduced boosting units that are specific to the percentage type aliens with the exception being apollyon who is the hardest of all. The boosters were made to asauge the insane effort and energy it required to get them low enough to destroy. Usually past 50% a percentage type alien will start dropping health much faster than before.
