Zombies and Orcs

You have discovered ways to quickly move using teleportation and when visiting new lands you will have to protect your portals so that aggressors do not penetrate them. Place defensive towers on which your soldiers will fire at those who follow the paths. Place walls and mines. For killed enemies you get experience that can be spent on upgrading your abilities and towers. Do not forget to use abilities that recharge automatically. The right decisions will lead to victory.
