Death Squared was release last year, on 13 July 2017, and since then it has sold over 52,000 copies of the game on the Nintendo Switch.
To (sort of) celebrate their accomplishment, SMG Studios announced that the game will be made free when they hit 250,000 copies in sales. If you linearly extrapolate the data, we should be getting the game free somewhere in 2021/2022, so maybe in the next World Cup.
Until then, you can still purchase the game from the Nintendo Switch eShop here.
Also when/if we sell 250,000 copies on the Switch we'll make the game FREE!
By then it'll be available on the Switch 2.0 and flying cars etc but also we'll have other games out there to focus on. So just another 198,000 sales to go!!!
