for anyone finidng it hard i found it best to sit right inbetween the enemy base and your base,,with your allied ships,they may hog half the kills but with you in there flaking anyone that gets past your allys the station takes hardly any damage,and you still get tall the ether you need to upgrade
by far one of the best games iv ever played,i find it damn near impossible to destroy the revlovling orbs let alone the big one they guard,but it gives a sense of a massive real battle,the musics great,the games great,10/10 from me :)
