The Engine: StarEngine
Originally built on a heavily modified fork of CryEngine (and later Amazon's Lumberyard), Cloud Imperium Games (CIG) now officially refers to their proprietary technology as StarEngine.
It is specifically engineered to solve a problem standard game engines can't handle: rendering a player holding a coffee cup inside a capital ship, while that ship flies inside a planet's atmosphere, while that planet orbits a star—all with zero loading screens.
From what I've heard the game is still one huge client sided miracle. There's all sorts of cheats and hacks popping up here and there. None lasts very long though atm.
Suggested features: radar, esp, aimbot, infinit fuel, infinite ammo, movement speed hack, weapon firing speed hack, no reload, unlimited clip, being able to use weapon in forbidden area's, god mode/infinite health, infinite stamina, infinite oxygen, expand inventory size (no backpack weight limit) (at everyones own risk ofcourse, but thats the entire thing this game is about... xD
Teleport?
(All mentioned things above that could go for either FPS mode and while flying a ship (god mode, infinite ammo, aimbot, etc) Please understand it as I meant to say both infantry and ship modes.
