Bubble gun＞Shotgun＞Pistol＞Electric gun

The bubble gun is invincible, just choose the number of bullets, range, reload speed, bullet offset, sacrifice, two kinds of dodge, various health recovery, projectile 1, and other bullet sizes (try not to add weapon damage, Affects hit trigger)

For skills, choose fireball. For other skills, you can consider using all projectiles. The disadvantage is that if you choose too many projectile bonuses, you will get stuck. For advanced ones, choose blood recovery, experience gain, and freezing. Other options are optional.

I always choose Magnet for missions, then hang up for the whole process. I just come back after a few minutes to select skills. When I get almost completely stuck at 80 or 90 minutes, I just give up. Apart from the boss, no other monsters can be seen, and everything outside the screen is dead.

The principles of shotguns are similar. Just don’t choose too many bullets. If you choose too many, the damage will not be enough. This is also where it is inferior to the bubble gun.

No matter which weapon you choose, choose Sacrifice early. Don’t dodge when you encounter the beam. With dodge and blood recovery, you won’t die. Skill points will reach thousands in no time.
