The goal is simple; destroy alien portals before they
destroy yours. Under the strict guidance of your will
is a modest turret.
It cannot be destroyed, but is stunned upon collision
with the enemy. Firing all out is not enough to
achieve
victory.
Even when you are winning, monsters can slip into your
portal. One can soon turn into ten.
Also, new portals teleport new monsters. Upgrade your
gun, place additional
slots, place the mines, pick up bonuses, do your best
to win. Adapt, improvise and transcend!
