To kill the giant (for those who don't know): Use your pasic arrows and hit the giant's exposed stomach when it lifts up its axe, and hit the giant on the head when it removes its helmet. Also, your archers can deal quite a bit of damage against that giant as well.
Needs a campaign mode with a storyline, ways to control your units, a strategic and satisfying victory instead of spamming units to win, and why am I even suggesting this when this suggestion is gonna disappear soon?
"Sir! Enemy approching in several seconds! Should we set up road blocks and defenses?" "No, we should just let them have a clear pathway with turrents to gun 'em down." "But wouldn't it be easier to just place a turret in front of them to mow 'em down?" " Shut up soldier, this is what HQ told me to do! Now do your job!"
A little walkthrough for Judgement City: Like Darkhawk45 said, Build a Spiderbot Factory first. But the amount of time it takes to spawn a bot in there takes a little too long, and upgrading that factory would take too much resources at the moment. So just upgrade the Creation Rate of the Spiderbots and hope that they will last against the enemy. NOTE: Make sure you place the factory in the front so that the Spiderbots can attack instantly. Then build a factory that can make bots fast, like the Green Factory. Upgrade the creation & speed of the bots, and if you have the money, other upgrades you want to use. Then build the Pyramid so that your bots can't be affected by the weather, and upgrade Creation, Speed, Power when you have the money. By this time, you SHOULD be able to hold off the enemy. Use your money on the other upgrades. NOTE: Use EMP when the enemy is nearly upon you, and when you have $75-90. You'll gain profit, and hold off the enemy. In the beginning, EMP is crucial.
Just a thought, but if listen closely in-game, you'll hear that they would want to kill anybody escaping because of the fear of a zombie epidemic....but I agree, why not kill the zombies themselves...?
I love this game....The music really adds to the mood, and it really affects your feelings for this man....how he had a career of an actor, being lonely all his life, the murder of his wife...How I cried for the sake of the main character....5/5.
