Invaders

Invader Detailed Stats & Mounted Weaponries
Invader Equipment, Health & Appearances

Effective Health of Invaders

Invaders can sometimes appear to be moving outside of your screen boundaries.

  • However, they are not actually outside of your straight firing main weapon's range, because the camera actually moves when you change sides of the field.
  • This means that there is actually much more horizontal space than you can actually see.

While Invader movements are mostly random, they follow a few rules:

  • They generally move within a defined boundary.
    • As the playing field size increases, the boundary of their movement also scales accordingly.
  • They move in bursts of straight lines.
    • The time and distance of the straight line movement is random.
    • The boundary stated above means that they also tend to move much more horizontally than vertically.
    • When they reach the end of the straight line movement, they will slow down, then they will make their next burst of straight line movement.
      • However, if the straight line movement ends up outside of their boundary as mentioned above, they immediately start their next burst of straight line movement without slowing down.
  • Invaders don't always spawn in the middle of their boundary zones.
    • This is especially so for Eagles that can move horizontally towards the center but can spawn at one side of the screen.
  • Generally, Ravens and Sparrows don't care if they completely overlap each other or other bigger Invaders.
    • However, Herons or bigger don't overlap more than half of each other or bigger.
    • Ravens and Sparrows spawn in a way the chances of them completely overlapping another larger Invader is pretty small.

The XP earned for killing each Invader-class is as shown below.

  • It is the same for all ranks and mission types.
  • When using revives , Invaders killed during the Act you were unable to pass through are also counted.
InvaderXP Earned
Sparrow 1
Raven 6
Heron 14
Eagle 24
Vulture 60
Condor 100
Roc 180

The XP earned goes into increasing your pilot level. There is no significance to pilot levels other than how much you have played the game.

  • A normal Level Up gives you ¢100 and 1 revive .
  • If you reach a level that is a multiple of 10, you will earn ¢250 and 5 revives .
  • If you reach a level that is a multiple of 100, you will receive ¢1.000 and 25 revives .

The XP required to reach the next pilot level is not well known. It is estimated to be 67.318 × log10(Invaders Killed) - 234. Note that different Invaders killed give different XPs, so this may not be the most reliable way, and the error of margin could be 5 pilot levels. Currently, the data collected up to Level 18 is shown below.

It is frequently accompanied by a "welcoming party" which can be as heavy as 2 Eagles and a Heron , or as light as only Sparrows . This "welcoming party" appears in front of the Condor and come in first. These smaller enemies will come in immediately while the Condor will take the full 3s to arrive.

A Condor can also arrive without any other accompanying Invaders come in when the wave starts. This only happens in daily and specialist missions up to Commander rank. For Marshal rank, a Condor can arrive in front of 4 Ravens behind.

The health of the different affinities of Condors are as shown. All Turrets on a Condor have the same health and are shown below.

It is frequently accompanied by a "welcoming party" which can be as heavy as 2 Eagles and a Heron , or as light as Ravens (+ possible Sparrows ). Sparrow only "welcoming party" is possible with only community missions .

  • These smaller enemies come in immediately while the Roc will take the full 8s to arrive after the wave counter has changed.
  • It is possible to have a Roc without any other Invaders come in when the wave starts, which occurs only in daily and specialist missions.
  • Invaders cannot appear behind a Roc.

The health of the different affinities of Rocs are as shown. All Turrets on a Roc have the same health and are shown below.

  • Unprotected = 810 HP. Turret Health = 48.6 HP.
  • Shielded = 405 HP Shield + 540 HP Body. Turret Health = 32.4 HP.

Trivia 1: All Invaders in Phoenix 2 are named after birds. However, Rocs are named after the mythical bird of the same name. In mythology, rocs have talons large enough to hold an elephant, as shown below:

Trivia 2: Here's a fun image made by the devs of an impossible formation of 2 Shielded Assault Condors and 1 Shielded Assault Roc. Note that Shielded Assault Invaders don't currently appear. Perhaps they don't seem to look particularly pretty? Also, most of the in-game effects (especially the cockpit flare of Condors and Rocs) are absent in this image which makes these Invaders look very crisp and clear.

Satellite

This special enemy only appears in Campaign Missions #24 & #25.

AffinityNone. All weapons deal normal damage. Not even High Impact weapons can deal critical damage.

Effective Health of Invaders

  • Armored Invaders have 90% health of Unprotected Invaders, rounded down to the nearest integer.
  • Invader Shields have 2/3 the health of Unprotected Invaders, while the health of Shielded Invaders after their shield is downed are exactly ½ the health of Unprotected Invaders, both rounded down to the nearest integer.

Here's a more detailed table showcasing the effective health of Invaders.

  • For Shielded Invaders [denoted as x+y], x is the effective shield health, while y is the effective health of the Invader after the shield is downed i.e. the Invader's body.
  • For Armored Invaders [denoted as a (b)], a is the effective health if the damage is ALWAYS dealt to the body of Invaders, while b is the effective health if damage is ALWAYS dealt to the cockpit of Invaders.
    • Unlike other invader-classes, a Sparrow's cockpit is completely protected by armor (just like Invader shields). This means a Sparrow's cockpit is functionally the same as a Sparrow's body.
    • This means non-Armor Piercing weapons will always suffer armor damage reduction when dealing against Armored Sparrows (and High Impact weapons cannot deal critical damage). Thus, the effective health for Armored Sparrows will be reflected as simply a without (b).
  • A red colored number mean that the respective health is lowered because of a High Impact weapon.
  • A blue colored number mean that the respective health is lowered because of a Shield Breaker weapon.
  • An amber colored number mean the respective health is maintained instead of increased because of using an Armor Piercing weapon.
    • A number in italics, bold & underlined means that the respective health is increased because of armor damage reduction.
  • Note that the effective health for High Impact weapons is calculated based on the average boost, taking into account the critical hit rate.
