Tomorrow's US PlayStation Store update will add platform puzzler 'Closure' to the Instant Game Collection.
That will make it available at no extra cost to US PlayStation Plus subscribers for the next several weeks.
Closure challenges players to work their way through tricky 2D platforming levels with a unique gameplay mechanic that revolves around light sources - things only become 'physical' when you can see them. See the trailer below for an idea of how it works.
As usual, PS Plus subs will also be treated to a new round of discounts; 80 per cent off Critter Crunch, 20 per cent off Alien Breed (Vita/PS3 Cross-Buy enabled), 50 per cent off Derrick the Deathfin, and 20 per cent off NHL 13.
Expect these updates and more in the US PlayStation Store update tomorrow, February 12.
