we used the almost the same tactic afer all... I think that is the only tactic that can be use to complete all objectives at time
...
When you look my video you will see:
1) I let bombers and fighters to kill the first 8 fighters
2) Order all to ignore the Sathanas
3) Order Alpha to destroy the Rear turret
4) Order Delta to destroy the Right Flak
5) When making the 1st Bomber run, always target the first turret of below. (why? see next point
)
6) Afer launching the first 2 bombs at the 1-below beam, target and destroy whit Trebuchets the left Flak*
7) Then Call in support and destroy one more turret.
8) Rearm
9) Destroy the last two beams
10) Rearm, 1 Helios at the Turret firing at the Thebes
11) Disable the Beleth
12) Destroy the remaining Beams on Beleth
13) Order all bomber to attack the Beleth.
14)
You will need a little of luck here... for the negative impacts on the fowar beams... and sometimes, Alpha will be killed before destroy the rear turret :S
Note: Under not circustances order the bombers to follow you... before the Sathanas jumps out
, that kills more than save xD.
*For some reason... the forward flaks take no damage from the front and upper parts... you MUST hit the structure below the flak to damage them... That why you must attack the below forward beam first... you will end in a excellent position for Treb fire on the left flak. and this is the same reazon of why you must always delta to destroy the right flak... sometimes, Delta will not destroy the left...
