Pig Farm Defense - Warcraft 3 TD
To the best of my knowledge there is not another WC3 TD that replicates the Pigfarm style. You basically have a square farm(base) which you an 7 other players are required to defend. Your farm is lined with empty towers which can be activated by moving in a pig.
You earn a new pig every time you kill 10 creeps. If you don’t want to activate a tower with your pig you have the option to sell it for 12 gold. This can be done by moving the pig to the pond in the sender or by typing in “sell all”.
Gold can be used to upgrade towers or to purchase heros. In most other tower defenses you want to build as few towers as needed and continually upgrade until you max out before building additional towers. In this game that doesn’t seem to be the most cost effective strategy. I suggest upgrading each tower only 1 time. Then after 4-5 upgrades purchase the archer hero.
Tip: To get extra kills early select both of your towers. Then hold down the alt key to watch creep hit points as they run around your towers. Then click on the weakest creeps.
