Curve Studios has put out a healthy amount of stuff on PSN, and is now bundling four of their available titles for $15 for two weeks, with a $1.50 discount coming to PS+ users. $15 gets you Lone Survivor, a survival horror game, Thomas Was Alone, a beautiful minimalist puzzle-platformer, the exploration game Proteus, and Stealth Inc: A Clone in the Dark – the most action-packed game of the bunch. Without the bundle, you’d be paying $45 for them, so this is a fairly significant savings. Bundles like this aren’t too common for regular PSN games, although they are fairly frequent for the Minis offerings. If you’re interested in a couple of them, you might as well snag the whole lot of them for such a low price.
