Poncle’s Vampire Survivors is teaming up with Konami for a crossover unlike any other. No, serious.

Instead of the obvious Castlevania route, the bullet heaven game is getting a visit from Konami’s run-and-gun shooter spectacular Contra via a new DLC called Operation Guns. It’s full of new characters like Bill and Lance (and Hard Corps’ Brad Fang) and new weapons like the Spread Gun. All these need to be unlocked by playing through the new Neo Galuga stage and using the characters you’re given. Here’s a guide on how to do all that.

Vampire Survivors: Operation Guns Contra DLC All New Weapon Evolutions

There are a ton of new weapons courtesy of the new unlockable characters. Here’s how to unlock characters & weapon evolutions.

Characters

Bill Rizer – Bill is in a coffin on the Neo Galuga map. Go all the way to the east; while you’re crossing the bridge, do get the map on the way to unlock the lay of the land. Once you tracked him down, just quit the game and purchase him on the character select screen to unlock him.

Lance Bean – You can unlock Lance by evolving Bill’s Long Gun. To evolve it, you have to get Weapon Power-Up which is available on the Neo Galuga map. Once the Long Gun evolves to Prototype A, just quit the game and you can then purchase Lance on the character select screen.
