Behaviour
All Aliens will simply fall from the top of the screen. If they hit the Player, they will die and infest the player's ship, inflicting terrible status effects for a short amount of time, or, if the player has purchased enough upgrades, until the player removes them with a core burst.

Types
There are 4 types, or colours, of Aliens, each one inflicting different types of effects.

Purple:
Purple Aliens, if they hit the player, will cut movemnt speed in half. They're probably the most common Alien, but also the most tame as far as effects go.

Green:
Green Aliens, if they hit the player, will, in addition to slightly slowing down movement speed, will prevent the player from firing their weapon. The player will still be able to use the core burst, but will not be able to shoot any kind of projectile.

Yellow:
Yellow Aliens, if they hit the player, will, in addition to slightly slowing down movement speed, will reverse the player's controls. This means that if the player tries to move up, the ship will move down, and vice-versa.

Red:
Red Aliens, if they hit the player, will stop all movement. Once the player is infested with a red alien, the ship will not be able to move at all. However, the player can still fire the gun.
