Swarm io online is a free tank game situated in a unique 2D world full of enemies. You step into this world to fight against them and try your best to survive all attacks here. Basically, Swarm.io unblocked is very the same as Agar.io in terms of gameplay. At first, you only begin with a small swarm of 2-3 tanks, and you have to move it around the map trying to grow its size by killing bots or taking down enemies. You should prepare some tricks and strategies in advance then use them to outplay other players. Be careful when you cope with deadly attack bots because they are everywhere on the map. They can become a great source for increasing the size of your swarm, however, they are sometimes very dangerous. You have to stay watchful for everything around you. Keep growing your swarm until you reach the top spot on the leaderboard. Good luck to you!
