OnePlus announced Tuesday, a very interesting utilization of the constantly developing 5G technology. Starting March 9, the smartphone brand will host an interactive 5G snowball fight.

The tournament will take place for 70 hours in Lapland, Finland, hosted by the Finnish mobile operator Elisa. Competitors will be able to participate in the snowball flight using OnePlus’ uniquely developed 5G Snowbots, which will fire snowballs. Users from around the world will be able to control the robots remotely on any device, battling aginst teams of humans on the ground in Finland.

OnePlus is orchestrating this snowball fight to demonstrate the potential of 5G to provide a lag-free offline-to-online gaming experience. The game will stream live continuously between March 9 at 7 a.m. ET and March 12.

OnePlus is currently hosting a contest on its social channels to select users to participate in the in-person side of the Snowbot Battle in Lapland.

We've created 5G-connected, snowball-firing robots (they fire at 120+ mph; we're not messing around).

We're calling them Snowbots. And you can control them from your phone to shoot Snowbots controlled by other OnePlus fans, from March 9. Get ready. #OnePlus5GSnowbots

OnePlus’ experiment comes not long after the brand announced a concept device at CES 2020 that features a color-shifting glass technology. The design makes it so the rear camera lenses on the device appear invisible.

Shifting beyond smartphones, OnePlus is also delving into other tech avenues, including smart TVs and audio. Currently, rumors suggest that the brand’s next smartphone, the OnePlus 8 may be announced in April.
