Guns of Icarus

Guns of Icarus is an Indie Game turret-based co-op shooter game set in a post-apocalyptic Steampunk world, developed by Muse Games. You are Gabriel, a traveling merchant, captain of the zeppelin Icarus. Your task is to deliver your cargo safely to its destination without being blown out of the air by the Sky Pirates that will chase you every step of the way. There's an element of time management involved--you've got to strike a balance between repairing damaged parts of your ship and manning the guns to shoot down the bad guys.

An MMO sequel, Guns Of Icarus Online, is currently in development.

Guns of Icarus contains examples of:

 * After the End
 * Constructed World
 * Cool Airship: The Icarus.
 * Co Op Multiplayer: Up to four players can play together online.
 * Critical Existence Failure: If the health meter for either the zeppelin or the rigging reaches zero, the Icarus will be destroyed, but aside from some fire graphics, there won't be any effect until then.
 * Death Is a Slap On The Wrist: If you fall off the Icarus, you respawn, but it does waste precious time. And if you fail a mission, you have unlimited tries.
 * Difficult but Awesome: It takes some practice to get used to the timing of the cannon shots, but if you get good at Leading the Target, you'll have a very powerful turret with a much longer range than the gatling guns.
 * Downer Ending:
 * Endless Game: "Into The Breach", where you hold out as long as you can until.
 * Enemy Detecting Radar: Absolutely vital for tracking the position of enemies, since your vision will be obscured by clouds and weather conditions, and you'll be attacked from all sides. If you don't watch the radar, expect to die.
 * Every Bullet Is a Tracer
 * Game Level: The "Lattice" variant. When selecting the next mission, you pick from multiple paths to make your way across the World Map.
 * Gatling Good: The first gun available. Comes with lots of dakka.
 * Hold the Line: Each mission has a distance countdown marking how much farther you have to travel to reach your destination; you have to survive and protect your cargo until the Icarus makes it to the finish line. There is a twist--enemies will attack your engines, which makes you slow down and, if they reach critical condition, stop completely, so you've got to keep them repaired. The final stage, Into the Breach, averts it by counting up instead of down for a survival mode.
 * Homing Projectile: Homing rockets.
 * Lead the Target: This is required if you're using the cannon.
 * Lightning Gun: The Tesla cannon.
 * More Dakka: The gatling gun's main purpose.
 * Sky Pirates
 * Steampunk
 * Stock Costume Traits: Standard pilot outfit with goggles, scarf, and jacket.
 * Subsystem Damage: Enemies can target different parts of your zeppelin. If your rigging or balloon gets destroyed, it causes a Critical Existence Failure. If your cargo bay is destroyed, it affects the rewards you earn for beating the level. And damage to your engines causes you to slow down and eventually stop. Part of the strategy of the game is prioritizing which sections to repair and how long to wait before repairing them.
