This Is How I Play Undead
You start
Send the ghoul to wood
2acaloyts to mine
1 acolyte make a crypt+zigg+alter then send to mine
make 2 more acolytes and put on gold mine
When the buildings are finished
make 2 ghouls and a lich
liches first skill frost nove
with 2 ghouls and a lich kill the spawn South of your base(if your playing bootybay(my fav <3))
do the same with the next spawn(theres 2)
somewhere in between make a graveyard and make some crypt fiends+2-3 more ghouls to get lumber
then once you have 3 crypt fiends,2Ghouls And your lich(around level 3) go attack the first gold mine it should have 4 or so monsters
Bring an acolyte to haunt the mine+ make a necropolis,
now upgrade your necropolis(at default base) to a halls of the dead
make another crypt and make 2 gargoyles at once until you have about 4
Then if you have enough get all the requirements for the last base one(forgot what its called)
make a sacrifical pit+boneyardx2 then start making dragons(last base required)
and keep in mind always have defenses around your base(upgraded ziggys(half nerubian half spirit))
now when you have max food limit of lich+dragons+gargoyles
Go attack Computer(easy) Depend on what race he is you have a good chance to win
Strategy for Killing his base:
Hopefully you're level 6 or above send in you're units(some melee+air) and keep your lich behind them Casting death and decay on their main buildings,
This is my usual Way to Kill Computers Cuz they not that smart
Rember To upgrade you're Units In the graveyard
You might want some abominations For melee tanks so your lich doesn't die:)
