Survival Mode 3.0

Survival Mode 3.0 came out on January 15, 2012.  There are only 60 waves; the waves do not repeat as in the previous Survival Modes.  After completing the 60th wave, you exit back to your empire with your units intact—this is a noteworthy change from the never-ending waves of earlier Survival Modes.  At any time, however, you can choose to pause or surrender. 

After successfully completing Survival Mode 3.0, the congratulations message shows the SF Goblin only, but you also receive one Tactical Nuke and 360,000 Coins for completing the last wave.  You can restart Survival Mode, but it starts again at wave 1.

Overall, the enemy units seem to be easier to deal with than in the previous Survival Modes.  If you use Tier 6 units, the waves don’t become difficult until around wave 40.  The last wave has 1 Blackbird, 2 Osprey Airships, 1 Advanced Drone Fighter, and 1 Hypersonic Bomber.

Other changes from previous Survival Modes are related to the rewards.  Instead of getting rewards after completing each Wave, you get them only after every 5th wave.  You no longer receive energy packs or ores, so ore-farming and experience-farming have been nerfed greatly.

Here are the rewards:

Wave	Rewards
5	3,000 Coins	Field Repairs I	Evasion I
10	4,500 Coins	2 Field Repairs I	Accuracy I
15	9,000 Coins	3 Field Repairs I	1 x 3 Element Z
20	I-400 Sub Carrier	Mustang Purple	Mule Robot
25	20,000 Coins	Field Repairs II	Hunker Down II
30	30,000 Coins	2 Field Repairs II	Explosive Ammo II

40	Doberman Tank	USS Enterprise	Elite Kettenkrad
45	120,000 Coins	Field Repairs II	EMP III
50	180,000 Coins	2 Field Repairs II	Poison Gas III
55	240,000 Coins	3 Field Repairs II	3 x 3 Element Z
60	360,000 Coins	SF Goblin	Tactical Nuke

Total Coins:  1,026,500 (5,132.5 ore-equivalent at trade value of 200 Coins per ore)

The unique units earned in waves 20, 40, and 60 (bolded above) are subject to change, as mentioned in the game screenshot below.

Think of it this way: if you finish one round of all 60 waves per day, you make around one million Coins per day! You also get this upgrade-able fighter:
