Ok I am new to this review thing so I'll try to make it short and sweet without boring you.
The game where you don't really need to work hard but you "do" need to work hard because there's always those new kids who ran across a load of equipment and got it taken away by you but then there's those who know how to play better than you and they take away "your" new stuff :). Really great gameplay for a free game, but others may say different. I myself and a lot of others would say it's not always the graphics that make a game great, but that it's the gameplay and storyline and all the little things that draw your attention like workshop items which include a lot of things like maps, guns, clothes, vehicles, etc. It has the feel to Dayz but Minecraft at the same time and is playable to those who could only dream to play big survival games because lack of the funds to be in the big league gaming computers, but other than that lets go to the Pro's and Con's.
-Gameplay of the game and flow.
-Workshop compatibility and simplicity of use to those who want to start producing items to those who professionally produce items.
-Ability to jump right into a server or game and get destroyed by a kid younger than yourself. Doesn't take much to play well.
-A well made group system to keep and eye on your team and foil your plans to smash your friends, that is unless you have a grenade. :P
-Constant new updates and content added weekly or daily keeping the game interesting and open to optimization.
-Overall fun and competitive sport with friends and the community.
-The occasional kid or "adult" who thinks he/she is a professional gamer or game reviewer, who thinks their thoughts are everyone's and that because the game is blocky, and not sculpted from the microscopic level, it is a terrible game and shouldn't be supported. -_-
Well I hope my review didn't take too long to read. If you did take the time to read I thank you and recommend you to check this game out, and I hope I see you unturned and thriving in the world of Unturned. :)
