Rust

With a blend of construction, first-person action and survival, Rust could very well be the ultimate online survival game. As you start your journey on the massive island, your meagre supplies will consist of two tires, a stone and a torch. If you expect to survive the dangers, wild beasts and other players for example, you will have to think fast. Make friends to help you on your way, but trust no one. Rust offers a nice combination of the most popular gaming genres. Each server has up to 300 players that share a large island environment. Similar to Minecraft, you will have to acquire materials, such as stone and wood, to create new items and shelter.
However, unlike Minecraft, the other players on the island are more than happy to take what you have and leave you laying in the bushes. This focus on conflict and survival is what sets Rust apart from other, similar games like Minecraft. You have to find ways to defend yourself, eat and stay warm. The game also possesses some nice visuals, but you will not be able to appreciate them without a powerful computer.
One of the drawbacks to the game is that the environments stay pretty much the same and become tiresome when crossing the seemingly never-ending rocks and grass. Even though there are limitations to the game, since it is still in the development process, Rust is definitely setting a new standard in the survival game genre.
