Limited Run Games will have both games up for sale on the 4th of July (with two start times for orders, 10am and 6pm respectively). As with all their games, you need to grab them relatively quick (probably have an hour or so from the time they go up).
Xeodrifter will be available for both ps4 and vita, with 2300 copies of each available.
Lost Sea will be available for just ps4, but their are 3000 copies up for grabs.
I have been collecting every ps4 Limited Run release, so I will be sure to be there to pick them up, but wanted to let TAY know as well so they can get a chance to grab physical copies of these games.
