Today I played on Mansor Network, APC(Apocalypse) it is a wave game, previously you defended crystals, but the crystals have been removed and you now defend yourself. It's alot of fun, you can play solo or with friends. I found even though I'm horrible with Shaman, sometimes the mobs are not the easiest to search for when a wave ends. You do have a compass that will lead you directly to them, BUT you also run out of hearts the longer it takes to kill the mob from the wave, in other words, there is a time limit they spawn in, after the time limit, then you have to hurry and find them before YOU die. Shaman and Necromancer are both really good for Survival. Personally I'm looking to Prestige my Mecha, but Shaman is really good because after the wave "ends" you can heal yourself quite a bit.
