Bombers

Bombers (aka UFOs) are tough mid-to-late game enemies that come in a total of 8 types. Their basic behavior is to launch bombs, act as carriers for Mini-Drones, and to launch fleas at opportune moments. This varies based on the type though. The damage and effectiveness of bombs is based on how close you are to the center of the explosion - being close to the center greatly increases the damage.

(General tactics/tips at the bottom)

Types: Blue: This is the most basic type of bomber. These will fire two blue bombs at a time and occasionally fire a small burst. If these bombs get close to the player they will slow down right before exploding. The player is greatly slowed if inside an active blue explosion.

Teal: This is the homing-type bomber. If the bombs get close enough to you they will make a circling motion to try to get close to the player. If they get close enough, or enough time passes after they start homing, they will detonate. These bombs detonate several times in the same spot.

Most importantly, if one of homing-type bombs locks on to you, then ALL homing type bombs will lock on to you for a coordinated attack.

Purple: Purple bombers act as area denial. Their bombs will slow down to a crawl so they take forever to leave the level. They usually slow down when they reach the same height as the player. When the player gets close enough they will explode four times towards the players initial position.

Green: These bombers fire one at a time, but can have a burst firing pattern. Being hit by a green bomb will reverse the player for at least three seconds, plus additional time based on how close you were to the center of the explosion. Being hit multiple times can leave you reversed for an extended period. It is recommended to use the Expansion Grenade to remove extremely long debuffs.

Red: Red UFOs are three times more durable than lesser UFO types. If you are underneath them, and about a third in any event, they will shoot three bombs at once. These bombs will disable your weapons for three seconds, plus additional time based on how close you were to the center of the explosion.

Dark: Both the bombs and UFOs of this type are very difficult to see. They can fire in bursts and have twice the health of normal UFOs. Their bombs implode - sucking you towards the center like a black hole.

Yellow: Very dangerous. The bombs on these will implode like the dark bombs, but then explode for more damage. They are most dangerous though because they carry yellow mini-bots. They will often launch a swarm of them when they fire their bombs for a coordinated attack.

White: These are the most durable of bombers with five times the health of normal bombers. Their bombs will occasionally teleport in order to remain over your head. If you are hit by them then you will be unable to use portals for three seconds plus additional time based on how close you were to the center of the explosion.

White bombers are most annoying because they carry white fleas. They will usually launch these fleas when your weapons are disabled so you don't instantly kill them with the Brain Bomb Decrypter.

Tips:

EMP devices will disable UFOs, but they fall slowly and will not take fall damage. You can do crush damage to them, but it isn't an insta-kill like it is with bots.

It is usually best to attack bombers from above to avoid, but because they are so large it is easy to hit them with Not-A-Shoryuken.

Try to kill the bombers quickly. They can cover the screen with bombs which often have disabling effects. They also tend to use their full capabilities when you are least able to deal with them.
