For starters, while quite useful, the Fuck-you battle fortress is inevitably a worthless weapon, pretty hard to come by, can't be every where at the same time (only 1 can be a fuck-you battle fortress) and is simply too slow to defend the base.
If you wish to win 1v7 meteor shower then please read this thoroughly.
I have thought of multiple strategies. And all of them can only be won using china. I am sorry, they just so happen to be the easiest to play with.
This strategy happens to work against all factions and sub factions.
For defenses 1: Use a team of 16 (or more) eradicators to guarantee immediate termination of all elite tanks (tyrant, colossus, ??? for psicorps, abrams etc.)
For defenses 2: Use a team of 30 gyro-copters to terminate to filter out any infantry from the attack that the AI will casually send against you, leaving the eradicators having only one target, the elite tanks.
For defenses 3: Use a team of 8 sentinels to eliminate all aircrafts that the gyro-copters were not able to terminate. Kirovs and a possible target of the sentinels.
For defenses 4: While it rarely happens, the eradicators do get quite troubled, 6 nuwa cannons are good for this, though I suggest they are trained veteran, so they can reach elite status easily and can repair them selves faster, I will prove why even getting spies into the warfactory in the first place is near impossible.
------ATTACK------
Attacking is near impossible when not properly defended, the enemy will try and take over while you're attacking, so I suggest that you put your troops where the enemies troops are coming from, this will thin out your attack force but it's better than risking losing.
Attack 1: 18 Nuwa cannons for long range attacks
Attack 2: 8 Sentinels to kill the 5(maybe more) battle fortress irkalla's
Attack 3: 16 desolators to protect the nuwas and sentinels while they're attacking buildings, though watch out for stingers, desolators are quite useless against them.
Attack 4: 20(maybe more) kirovs as plan b
------SPY------
This is why spying is impossible:
The enemy builds about 5 war factories, each one will produce one terror drone, given that the enemy produces 2 terror drones as base defense, you will have 10 hunting your spies down, while the damage they will get from the saboteur explosion will be lethal if in large numbers you will need to spend tens of thousands of credits on saboteurs, this is simply useless using any other spy unless amassed in incredibly large numbers.
------OTHER STRATEGIES------
Allies strategy: Replace gyro copters with rocketeers, nuwa cannons with thor gunships and mirages, eradicators with Siegfried and navy seals.
That's all folks
------CRITIQUE------
This plan is quite flawed, I thought of it a week ago, tried it 2 days ago and won using it 1 hour ago, for all I know that could have been luck.
So please, give me ideas so that the official guide to winning 1v7 meteor shower(3.0) is improved.
