Drainus Is a Perfect Name for a Shmup—and a Great Game, Too
The Shmuptake #9: It Is Now My Duty to Completely Drain You

Welcome to The Shmuptake, an occasional column about the history of the shoot ‘em up, aka the “shmup.” Here’s an introduction, and here’s an archive of every column so far.
Drainus is an apt name for a shoot ‘em up. With its arcade lineage, this is a genre built on draining the player—originally of their quarters, later of their patience, stamina, and mental well-being. Shmups are all about the marriage of repetition and escalating tension, where you do the same thing over and over while somebody steadily twists a knob that amplifies every aspect of the game. It’s the videogame version of somebody gradually pushing a needle deeper and deeper into your skin, while you grit your teeth and find yourself enjoying the pain. “Drain us,” shoot ‘em up fans demand, and that’s exactly what Drainus is here to do.
Team Ladybug’s 2022 shooter arrived on the Switch in early February, nine months after it was first released for PC. If I had played it then it would’ve easily been near the top of my year-end list. As is, it’s the first great game I’ve played in 2023, and a must-own for any shoot ‘em up fans with a Switch.
Most shooters have a hook, and with Drainus that means you can inhale the enemy’s fire and shoot it back at them. Drain their shots to drain their life: that’s the Drainus way. You absorb those shots by triggering a shield around your ship, but that shield has a short life span and can’t block or soak up certain types of projectiles; those bullets will hurt you even if your shield is up. Knowing when to trigger that shield is perhaps the most crucial key to success. Some enemies can only be defeated by absorbing energy and firing it back at them, including one particularly difficult boss battle that takes a lot of patience and delicacy.
Beyond the shield gimmick, there are two things that distinguish Drainus amid the shmup set. The first is its deeply customizable weapons package, which operates on a five-tier upgrade system. Upgrades and power-ups can be purchased at any time through the start menu, using energy tanks that slowly fill up as you defeat enemies as currency. There are five tiers of weapon upgrades that your ship climbs as you collect power-ups during a game, and they effectively act as a health meter, too; so if you’re in the middle of a run and have grabbed three power-ups, then you can take three more hits before you die. Of course every time you’re hit you lose whatever weapon upgrade that most recent power-up unlocked for you, and trying to maintain as many of your five upgrade tiers active as possible is a major and constant part of the game’s loop.
