Outcast is a 3D third-person (with an optional first-person view) action game with adventure elements. In search of five sacred relics, the protagonist travels through the five continents of Adelpha (plus one tutorial island). Each land has its own landscape (mountains, lakes, forests), populated areas, as well as dozens of minor problems - small quests that the hero is required to solve. Most Talans populating the world can be conversed with about a variety of topics. A large portion of the game consists of finding key characters and performing quests for them; some of these are optional, though most must be completed in an adventure-like linear fashion in order to advance the plot. Cutter is free to travel between the continents using special portals. Apart from exploration and completing quests, Cutter will also fight many guards and creatures. At his disposal are six futuristic weapons (railgun and others); ammunition for those guns is scattered around and can also be produced by mixing items. Aiming help is provided in the form of laser sights. Sneaking up to the enemy and punching him out silently is also possible. Gadgets such as a holo-decoy can be used to help Cutter gain the upper hand in combat. The player character can also jump, climb, swim, dive, crawl, and ride a local animal known as Twon-Ha for faster travel.

Shattered Skies raises open-world sandbox looter-shooter style games to the next level. Step into a massive experience set in a world where all hell has broken loose. A comet impact has shattered the moon into countless pieces which were pulled down by earth's gravity along with fragments of the comet itself, resulting in thousands of meteoric impacts. Areas that meteor shards landed have brought strange crystal growth formations all over the world and remaining humans are just now discovering how to harness this great crystal energy, granted they can survive the monsters lurking in a dense fog near the crystals.

A thousand years ago, a cataclysmic event shattered a world into floating islands scattered across an endless skyline. Civilizations tumbled, societies collapsed, and all seemed lost. From the rubble emerged ragtag bands of nomads, who fly cobbled-together skyships from island to island, scavenging for resources to keep moving. These are the players of Worlds Adrift: Explorers of a new world and seekers of ancient knowledge. Within the coveted ruins of the past, cryptic and forgotten fragments of the technologies developed by civilizations who built much, and over saw the collapse of it all. Harnessing such forgotten knowledge, players build greater and more powerful skyships that carry them further, past the crushing wind walls, through devastating lightning storms, to entirely undiscovered islands holding the mysteries of an earlier age.

Crackdown is an open world, third-person shooter video game for the Xbox 360. Set in the fictional Pacific City, the player controls a biologically enhanced Agent, tasked with defeating three crime lords and their organized crime syndicates. The Agent's abilities improve by defeating both crime lords and their supporters, as well as by completing optional activities, such as street races and scavenger hunts. The gameplay is nonlinear: instead of following a rigid mission sequence, players are free to select the approach to completing their missions and activities. The game features a two-player cooperative play mode via Xbox Live. Crackdown, initially planned for release on the original Xbox console, was envisioned as a vast world in which players could experiment and explore freely. Microsoft Game Studios bundled specifically marked copies of Crackdown with an access code to the multiplayer test version of the much-anticipated Halo 3 Beta. The game sold 1.5 million copies in its first six months of release because everybody wanted to play Halo 3. It received positive reviews and has garnered several awards for its innovative gameplay. Crackdown was a free download (for Xbox Live Gold members only) from August 1st, 2013 to August 16th, 2013 as part of the Xbox 360 "Games With Gold" (Xbox Live) program.
