Another Epic War, same problems, Heroes take a while obeying your commands because they're always half way through their attack which takes forever, linear game and upgrade system, you never really feel that you're in control and rather the game is.
Tips for winning on Impossible: 1) Choose smallest city size 2) Expand behind malls and 2 square buildings, they make it easier to clear out zombies when they start massing. 3) Expand to corners (having the smallest city size helps alot here) zombies don't appear on edge of map 4) Clear out the red squares around your fort and build farms rather than scavenge because the more soldiers, the more defence. 5) Research all the farm tech quickly, the more food, the more soldiers you have. The last tech is amazing, +1 for all farms. 6) Go for the helipad victory if you can, it's the easiest.
I just got the impossible badge. Some of the bonuses on the levels may seem impossible to obtain but try jumping on the furthest side of some blocks to rotate differently. It makes some of the runner/skater bonuses easier and some levels require you to do this, such as skater's 11th level. (At the vertical 3 block high chunk at the start jump in a way where you will rotate while hitting it on the right side)
How to avoid the final bosses attacks:
Missiles: Start at bottom right corner, move slowly along bottom for the first two launches, then move up and between the clump of missiles and the third volley of missiles then repeat.
Bullet stream: Locate a diamond of clear space near 2/3rds to the bottom on the right side and stay inside, making very slight movements left then right. You will get hit a few times at the end.
Pulse attack: Instead of looking at your ship look at the boss to find places he's not firing the pulse attacks.
Upside down V attack: Use the lower right corner, avoid the bullets firing down then move up to pass the slower bullets.
This game is a huge disappointment. I got a PC that can run Crysis at the highest settings, but if I play this and attach a super heavy machinegun it lags uncontrollably in the further bubbles. I'm pretty sure all the other Bubble Tanks games never had this lag issue. Fix the lag!
