As the Summer Sale continues, so does our ongoing list of recommended games. Interesting projects and solid discounts await within.

Stasis

The Brotherhood | PC, Mac

Combine the bleak industrial corridors of Ridley Scott's Alien with isometric adventure, and you get the grim gory Stasis. Sci-fi horror set aboard the isolated vessel Groomlake, you roam its viscera-soaked halls and dimly-lit rooms, where inhuman horrors and other threats lurk. Logical puzzles, creeping dread, and detailed isometric art deliver an effective unsettling adventure game.

Parallax

Toasty Games | PC, Mac, Linux

You've solved puzzles with portals and programming; Parallax challenges you to solve puzzles with parallel dimensions. Throughout its minimalist monochrome levels, doorways take you to parallel versions of the levels, allowing you to bypass or manipulate areas in both worlds. Shifting gravity, rotating platforms, and other elements expand on the game's spatial conundrums.
Prophour23

The Secret Pie | PC, Mac, Linux

There isn't another tower defense game quite like Prophour23. One might even question if it is a TD game since your tools aren't towers, but rather biological organs and body parts. To stop and defeat an onslaught of ravenous insects, you need lungs and heart for energy, muscles to power defenses like thorny barriers, eyes to light up the darkness, a mouth to yell at and slow down the crawling horde, and more.

Sun Dogs

Royal Polygon | PC, Mac
