This is a very good game in term of gameplay mechanics and technicalilties, but by biggest objection is that once you get to mission 14 and above it becomes physically impossible to beat the enemies without buying the premium currency. To beat some of the shadow elites I would need the top tier Tyr and Freyja units. Unlocking them requires hundreds of chaos, which would take weeks to months worth of gameplay to farm. The only other option is to spend "kronos" to unlock them or to buy chaos.
While this game is more developed that your run of the mill online flash game, it is definitely not worth spending money on. With this in mind, I am quitting halfway through the game rather than choosing to waste excessive amounts of time or money to be a good player.
