Embryo

Embryo
Embryo (Production Overlord) - first of the bossess encountered in Assault Android Cactus.

Phase 1
In the first phase, Embryo shoots regular bullets (in bursts) in the direction of the player. The best way to avoid them in most situations is to stay close in front of him, where his projectiles fly on the sides of player's character. You can also circle around Embryo to make sure you collect all points he drops. A powerup is dropped after finishing this phase.

Phase 2
In the second phase, Embryo shoots regular bullets, this time around himself. He attacks in bursts in this phase.

Phase 3
The third phase is the one the player has the most control in, as the boss shoots missles falling front the top of the level. Embryo drops a powerup after this phase.

Phase 4
The first phase players easily die on. It's a more powerful version of Phase 1, with bullets shot at higher rate and speed. To avoid it, the character has to be set like in the original phase, directly in front of Embryo, or really far away, inbetween streams of bullets.

Phase 5
This is an expanded version of Phase 2. After shooting a few bursts Embryo begins to eject small walls of projectiles around him. This phase ends with a powerup drop.

Phase 6
A combination of all phases, Embryo shoots out bullets in a new pattern as well as missles.

Tips

 * 1) Even though shutdown powerups are dropped right after killing different stages of the boss, using them after he recovers from that is a good idea.
 * 2) In the last phase the easiest way to avoid all damage is staying close to Embryo, slightly to the left so the front stream of bullets misses.
