The indie developer of intriguing sci-fi puzzler Reset has shown off the game's intriguing time travel mechanic for the first time.
Reset has been described as a co-operative single-player experience - the second character in the game is an earlier version of yourself that you travel back in time to join.
Sound confusing? It's all explained and demonstrated in the new footage below.
It's been a while since we've heard anything from Reset, an atmospheric indie adventure likened by its creators to both Dear Esther and Portal.
Two-man developer Theory Interactive has finally resurfaced with a new look at the game and fresh hints at its puzzle-filled gameplay.
The trailer below shows off a dark and rain-spattered city inhabited by two exo-suited figures. The game's major twist is that both of these people are you - one you control, and another a time-travelling version of yourself required to help with the two-man puzzles.
Alpo Oksaharju and Mikko Kallinen are the two men behind Reset, the upcoming single-player co-op puzzler that has spawned one of the most intriguing trailers of the year so far.
Together, Oksaharju and Kallinen are Theory Interactive, a Finnish indie PC developer that quietly began work on Reset "from scratch" in late summer last year.
But in contrast to the project's humble beginnings, the past two days since Reset's first trailer released have been "crazy", Oksaharju told Eurogamer.
