Project Ion is an MMOFPS/TPS/RPG that is in development since late 2011.

The project is under constant development but has a playable version up all the time.

You make a your own character that you will build up with skills. You spawn in the Zion underground starting room where is one NPC that makes you do some starting quests ( will be better in future ), at start you should start looking for someone that would help you around the game and explain you how game works because at start you dont have any money to spend on to buy armor, weapons and ammo to hunt mobs.
