heres a screenie for evereone who cant beat poison
First build the collectors in the black line then build a mortar on the red square and buil the blasters as soon as possible.
then build a mortar and let it load then move it to the yellow square and you wil see a part of the creeper fading away. as soon as the mortar is nearly destroyed move it back and build the relay move the mortar next to the one on the red square. the let the other mortar attack as soon as the relay is ready and when possible connect the mortar with a other relay if needed move the other mortar to it you should figure out the rest yourself ;)
have u checked out my custom map version?
I think its harder, but it at least looks cooler, (refering to the creeper and collector coverage colors)
Thank for your appreciation. :)
