Today one spider spooked me and I thought about ability to kill spiders in-game! (Just joking). So I imagine a boss that looks a bit from Space Crab family, but spider.
As you can see, it had 8 2-part legs with thrusters on joints. On the body there are 4 lights that displays health:
[* * * * ] - 100%
[* ° ° °] - 40%
[* ° ° °] Blinking red - below 20%
Fast attack: Dotted line. After 2 seconds he will quickly direct his legs in this direction
Flying attack: he will turn on his thrusters and start to fly around to kill you (not so dangerous attack)
Slowing: He will throw a web at you from gun so you will move slower (At 60% health)
And the final one (At this moment): Shooting something like big ion blaster at player(no photo).
Suggest your ideas to improve this bacchanalia.
