Up until this point, Star Citizen has basically been known as that one crowdsourced game that raised over $40 million for its development. Cloud Imperium Games took the opportunity at PAX East to show off where all that money went, and it is pretty impressive.
Star Citizen is being released in separate pieces called modules. The live demo showed off many interesting aspects of the gameplay in the first module which introduces refined space sim combat. Interesting features like the implementation of G-forces that pile up and can cause the player character to black out if too many maneuvers are taken too quickly. Various ship components can be damaged and impair ship performance.
There are still a bit of time to secure access to the alpha release of Star Citizen. To purchase early access, head over to the store on the Star Citizen website.
