Alien Hominid HD is a remastered release of the original Alien Hominid, which made its debut around 21 years ago as a flash game on Newgrounds. The game, featuring hand-drawn animations and side-scrolling actions went on to form what would become a signature of the studio’s general style, especially when compared to its future releases like Castle Crashers.

Of the two releases, Alien Hominid Invasion is a new title that will feature a variety of options for fans of co-op side-scrolling action games. Alongside its general gameplay, the title also offers a variety of difficulty levels, with the difficulty being set per-player, allowing those playing on Friendly difficulty to play with those playing on Insane.
