I have beaten Se 2 about five times. Dude, believe me and that other guy when we say the goliath is the best choice. Upgrade armour and get close to buildings. Also, the easiest way is to be near the invincible barracks on the hill, and just keep using the explosives to destroy the spawn barracks in the valley and on the next hill. It makes it really simple. After that, just destroy the Command Center. And finally, when you are fully upped, always do drops on the spawn buildings with the goliath spawns. Lastly, when your trying to destroy the canons and you got maybe 30 minutes, simply choose the ghost hero (you should have tons of cash by now as goliaths), upgrade armour like mad, then get some goliaths to protect the ghost and nuke. After the canons are destroyed, simply nuke the German HQ once to destroy it. I agree with you, its an insanely fun and challenging map. Panzer_Kavalier is a really good map maker. So, try that and tell me if it works for you, 'cause it always does for me!
