Slain.io presents a different kind of survival/ defense game. Start off as a level one noob and manage to survive against spinning spiked npcs and other players. With experience, you can upgrade and become one of the bigger and stronger noobs around.
At first your attacking skills are going to be next to nothing, be sure you might have a kill before taking on other players. You have 9 trainable traits, upgrade them by accumulating enough points on your experience bar. You might want to acquire some speed early on in case an escape ensues.
