The slots in the casino have amazing odds. 1/6 chance to get an octo per slot. SWEET. Until you realize you need four of them. Then the odds increase to 1/2500. That's a 0.04% chance of getting the octo jackpot. To get the 5000 reward, you need to spend 25000 credits.
Just a few tips...
1. Get the +1 charge powerup for crypts ASAP, and make sure you put them on most high-ground tiles.
2. The burning temples can kill stealthed ninjas, as with meteors.
Alright zombies, listen up. You will only attack a hut defended by a single man, with a pistol. You will ONLY attack from the west, because he has built a fence facing the west. Completely ignore the fact that he's on a hill, and no one is in the hut. Also, please resist the urge to make use of this opportunity to start a zombie apocalypse. This target is of much higher priority. Carry pocketfulls of cash, and make sure to attack in waves. That is all.
God. I find this annoying as hell to the point where I'm minusing every retarded little "5/5 cool" or "try it before you rate it idiots 5/5". State why the hell you consider it a 5/5, and we really get it with all the "try it" comments. Personally, I rate this a 3/5 and BEFORE YOU MINUS ME I've just had trouble with the game on too many occasions.
Adding onto NDstuctible's guide, after you get the Tec-9 you should be able to max out scavenger, and get your assistant to an SMG. After this you should get the barkeeper to a twelve-gauge, and save up until you get the M4.
New Jersey wiped out, 16mil dead, but I won! :D I tried killing it in Nebraska, and that was successful, but some damned Mexicans brought it into Texas. ._.
DO NOT LEAVE ROADS OPEN. This is my no-fail strategy where your wall will never fall. Play as Britain, with the attacker being France. Now, on every level make a fort of sorts out of palisades that secures your base. Try to build farther away from your base, but on Last Stand make 3 walls and on Les Champs De Gloire build past the bridge. The fort should be 1 rank deep full of Redcoats at the very first wave, with 1 rank of barricades protecting them from fire. Then make a 2nd rank of redcoats. Save up until you can get greenjackets and upgrade every redcoat. Then get puckle guns, they're really good. I hope this will help. :) Usually the enemy trys to creep around your base, but the barricades protect your wall and soldiers from damage.
Easiest game I've played in a long time... The ONLY "challenging" and "strategic" level there was was the goblin level on epic and even that was just spam with shield. The people who find this game hard fail horribly at gaming...
