I recently found out about this game, because i watched a german Streamer.
This game is called: Ark Evolved Survival and is basically playing Jurassic Park haha^^
You land on an Island naked and your goal is to get resources, craft items and tame Dinos!
Its an online Multiplayer game, there are around 70 Players on a Server.
I bought the game and its amazing!
The only downsides are: It's Alpha! But pretty well made for alpha state and it will be fully released in 2016.!
And you need a fucking high end pc ^^ Right now it's terrible to play because its lagging but they are workin on it!
