Gunbox.io is not your typical IO game. Yes, you do run around the map and you do attack other players with an arsenal of varying melee and ranged weapons. Where it gets different, however, is in the building aspect of the game. You can dismantle walls and build new blocks with different properties to protect yourself or create obstacles for your opponents.
Although the design of this game is nothing special, the addition of building mechanics brings a new level to the usual deathmatch gameplay. If you haven't already, try Gunbox.io!
