Fly through the air in the extremely inefficient way of gun recoil. The burst mode activated by pressing two attack buttons at the same time is All health, 3x attack and significantly increase charge speed Instead, full life recovery. If you're going to die, use it and bet on the reversal!

About this game
Fly through the air in the extremely inefficient way of gun recoil.
Use of sub-weapons and the final use of the Burst Mode is the key to stage clear!
■Tricks
Consume energy just by shooting shots.
It's easier to clear and have fun playing if you climb with momentum rather than fine braking.
When you can't attack the enemy well with recoil Use your secondary weapons wisely.
The burst mode activated by pressing two attack buttons at the same time is All health, 3x attack and significantly increase charge speed Instead, full life recovery.
If you're going to die, use it and bet on the reversal!
■By the way...
Even if it bursts immediately after the start It is designed to clear all stage.

Modifications to controller inputs
As a countermeasure when the controller input may not work Improved default key placement for games. If you could not enter it with the previous settings, you can install it again after uninstalling. It will be updated to the corrected input settings. * If the controller input still does not work Steam>setting>controller>『Controller Settings』 Turn off all controller Steam Input enablements. {STEAM_CLAN_IMAGE}/44284544/89a6a7a8ab4842b378eea6977ede5b7b920be1f1.png *Because Steam's functionality interferes with the input originally provided by the PC, It works fine with it.Read full article on Community Announcements (daisessen)
