Much as they did with Splatoon, Nintendo has been providing a lot of free content for Splatoon 2 since its release, and this trend is continuing into 2018 with a bang. First announced back in November, a new map entitled Shellendorf Institute is getting ready to drop tonight. The map officially launches at 9:00 PM EST (6:00 PM PST), so get your squad together and start preparing for a crazy night at the museum!
