• Cosmic Horror - If the player has [Abyssal Tentacle] , black holes fire three tentacles while active.
• The black hole will also attract friendly projectiles; however, beam type weapons will not be affected.
• The black hole will not attract projectiles that aren't moving, such as Blockner 's shields.
• Most enemies killed by the black hole will not drop .
• Black Hole Gun is one of the best guns for clearing rooms as it can kill a whole wave of enemies with one shot while removing all projectiles.
• In boss fights it is best to switch to other weapons while the black hole is traveling. This increases damage output while saving ammo. Beam weapons are the best choice as they are not affected by the black hole.
• The shots can suck up all boss projectiles, including the Mine Flayer's mines, the Dragun's knives & RPGs, etc.
• If combined with any high-ammo weapon using [Duct Tape] or used with any item that grants multishot such as [Scattershot] , it becomes a way to easily beat every boss without taking damage. Especially when used with the Cosmic Horror Synergy.
• Interestingly, black holes appear to make the player immune to bullets while present, even if the bullet appears to hit the player. This can be seen most during Agunim 's R&G Dept. fight and when fighting Shadow Magician , as their "bullet lightning" attacks cannot damage the player while a black hole is present, even if the bullets from the lightning pattern visibly connect with the player.
• The visual distortion effect that black holes cause can stack with each other, and as such, the distortion effect intensifies if multiple black holes are present in a small space.
• Since the black holes are technically bullets, they will be deleted by a Bombshee 's screech.
