Play EvoWars.io game at SonicGames. You are a mere caveman and every time you level up, your weapons and skills will also improve. You can level up by collecting the energy spheres or by killing another player. The bigger the opponent the larger the area of their attack so be very cautious in being near to them. If ever you find yourself being close to any of the intimidating players you can always use the speed boost to dash you out the place but every time you use that skill, it deducts your current xp, so better use it wisely! There are 25 levels and evolutions to unlock.
