Nex Machina (boss)

Nex Machina is a boss that's encountered if the player completes an Arcade playthrough on Experienced difficulty or higher with a single credit (no "continues"). It appears immediately after defeating Supreme AI and is thus the true final boss of the game.

General
The Nex Machina fight is considered to be an especially hard one, especially for beginner level players. After all the hard work needed to complete the game without ever using a "continue" the player is "rewarded" with a demanding high intensity fight. The fight patterns are the same for every difficulty but the speed of the fight increases with them. On Master and Hero difficulties revenge bullets are activated and anything you destroy will shoot back at you. In general, whatever secondary weapon you had when you defeated Supreme AI gets replaced by the Laser, which has special characteristics for this fight (no recharge time). It is generally known that Nex Machina is particularly vulnerable to dash explosion damage, so you shouldn't be scared to dash into it whenever you feel safe to do so. Beating Nex Machina 100 times, on any difficulty, is a Feat of the game.
