A wonderful game, only 3 stars way to many glitches I now have three task that I can't complete, Items that I need to finish a task are just not there, the one I am currently working I need to destroy a machine to move on, the machine disappears from the game during battle sequence, I have logged out and back in again just to redo the battle again only to have the machine disappear again I'm supposed collect a antenna at the end of the battle I found it but it won't let me collect until I destroy machine, one other glitch I need to find a ceremonial mask to complete mission after destroying machines can see mask but won't let me collect it, I don't mind glitches but when its the main objective in the mission that's aggravating.
