Update from April 28 at 1:05 p.m.
One of the game’s main developers, Mike Zaimont, spoke on Twitter about this surprise launch … which he himself was not aware of. He specifies that this Switch port is based on an old version which does not include the local Coop and New Game + modes added on the other platforms via an update in early April. "The Switch version in itself is good, the group in charge of the porting has really done a good job. It runs at a stable framerate, even in portable mode. (…) This launch is not representative of the standards of quality of Lab Zero. I'm sorry. It's not up to us, "he said.
Update April 29 at 9:45 a.m.
A post published on the game site finally comes to clarify the situation. We learn that Indivisible was initially to launch on Switch in early May, but because of "a series of unexpected events", the game landed prematurely on the eShop. An update will be "soon" deployed: the Rotir companion will be unlocked for everyone, optimizations at the CPU / GPU level will be made and the resolution will pass in 1080p in TV mode (720p currently). The Coop and New Game + modes are not mentioned. Finally, concerning the physical versions, we will have to be patient.
