If you're not familiar with ASMR, it stands for autonomous sensory meridian response and by definition is characterised by a static or tingling sensation on the skin. There are a vast amount of ASMR videos on YouTube, which relax listeners with both gentle and soothing sounds. Even video game companies have been getting in on the action recently - with Nintendo promoting The Legend of Zelda: Breath of the Wild in a unique "sights and sounds" clip not long ago.

Now, Australian-based developer SMG Studio – responsible for the wonderful co-op puzzle game Death Squared and other titles such as Super One More Jump – has hopped on the bandwagon by releasing a 25-minute ASMR video to help prepare "your mind and your body" for its latest Switch eShop release, OTTTD.

In case you're wondering, the title stands for "Over The Top Tower Defense" according to the developer and the entire video above explains much more about the game. If you don't have time to set aside 25 minutes to watch it – and find one of the 20 hidden eShop codes within the video – then here's a bit more about the game directly from the developer PR:

We describe the game as “Spaceballs meets Starship Troopers”. But anyone under 30 has no idea what Spaceballs is (their loss) and legal said we wouldn't be allowed to say that... so we fall back on “It’s an anything-goes TD game that doesn’t take itself seriously.

As for the story, here's what it is about:

The year is 2136. You work for HEROCORP™, the universe’s 4th largest private military force. Your job is to ‘preemptively defend’ the Earth against alien dimensions. As long as you complete the missions under budget and fill out the TPS reports in triplicate, everything goes smoothly. Dimensional travel is facilitated by HEROCORP™ rift technology, which is kinda like Stargate but we’re hesitant to throw that in the mix when we’ve already mentioned Starship Troopers. Is pre-emptively defending Earth ethical? Who cares when the money’s good!

The game includes 25 story missions, three difficulty levels, 12 tower types, seven heroes and multiple weapons, skills, abilities and armour options to choose from. If that wasn't enough, the Switch version even has some special Easter Eggs:

We know the Switch players take their game icons seriously, so we’ve set up Death Squared & OTTTD’s icons to form the first part of a triptych. We’ll be updating Super One More Jump and all our future games to form one continuous artwork.

And lastly, here's the proper trailer:
