At Sony's E3 2015 press conference, Hello Games showed off new gameplay of its ambitious space exploration game No Man's Sky.

Hello Games cofounder Sean Murray began the demo in a hangar, then launched into an ongoing space battle. Murray claimed the game is a "universe-sized sandbox", and that these kinds of battles are taking place across that entire universe. Players will be able to take sides in those battles, which are being fought by warring factions. Or they can pick a star on the expansive universe map, and travel there to discover planets and lifeforms.

Once planetside, players can find beacons to upload their discoveries to the wider universe. In the demo, we saw some sentinel robots attack Murray as he explored the planet, and modified the fully destructible terrain with a futuristic weapon.

No Man's Sky still has no release date--Murray said one is coming soon--but it will be releasing first on PS4.
