The Indie Royale game bundle site features eight independent games available at a “bargain.” Here is how the Indie Royale bundles work: the more people that buy the bundle, the more the price increases, unless people begin paying more than the minimum cost, which drops the price for everyone else.

Here are descriptions and trailers for the games included in the Summer Bundle:

First up is award-winning arcade real-time strategy game from Oxeye Game Studio, Harvest: Massive Encounter, co-created by current Minecraft lead coder Jens Bergensten, and downloadable for Windows and Mac, and is also available on Steam. This RTS/tower defense title offers battles of epic proportions with a unique style of resource management and exploration.

Next up is a brand new update of a classic point-and-click adventure game from SkyGoblin Games, The Journey Down: Chapter One available for Windows and Mac, Play as Bwana and his trusted sidekick Kito, who are struggling to make ends meet at their run-down gas station, as they embark on a spine-tingling adventure far from home and into a twisting plot of corruption and danger.

Also making its bundle debut is the long-lost Serious Sam II, Croteam’s twitch-tastic 2005 shooter sequel.

A four-pack of top imported Japanese games from Rockin’ Android also make their debut in the Indie Royale Summer Bundle, starting with all three games from Platine Dispositif’s Gundemonium trilogy, available for Windows on Steam Gundemonium Recollection, GundeadliGne and Hitogata Happa. These three games, which span both horizontal and vertical scrolling, offer a remarkably complex yet flexible experience as you enjoy bullet-hell shoot-’em-up gameplay in a cartoonish steampunk universe.

The fourth game from Rockin’ Android is Orange_Juice’s Acceleration of Suguri-X Edition, available for Windows.

Finishing everything up in the Indie Royale Summer Bundle is Dino Run SE from Pixeljam, available for Windows and Mac. This pixel-heavy indie classic is presented in a Special Edition, enhancing the Flash original with speed runs, extra multiplayer maps, hats, and other notable upgrades. The game is based off a pixelated prehistoric world, where players escape the inevitable doom wave of extinction by controlling a speedy raptor across tar pits, crumbling hillsides and meteorite showers while gobbling up anything that gets in the way.

As a one-off bonus, the bundle also includes another chance to get your hands on a Steam Windows Beta key to hot F2P action-RTS AirMech with a bonus in-game item: an exclusive Indie Royale “Fleur de Lis” companion/pet for your AirMech! Excusive to the Summer Bundle, this is one of the very first cosmetic items for AirMech. The game is still in closed beta on Steam right now, making these codes very difficult to come by.
