The Safeguard Garrison is a tower defense type game where the player is in control of different upgradeable towers and has to plant them through the level. They must be planted the way that enemies don't get the chance to infiltrate the friendly safehouse.
There are 50 levels in total leading you through The Arctic Meadows, The Desert Dunes and The Sunbeam Islands. The number of waves per level varies from 5 to as much as 12 waves, so plant and upgrade carefully.
UPGRADES AND PERKS
There are 12 different towers for planting and each one has 3 levels of possible upgrade. Also, there are more than a few unlockable and purchasable perks for you to rock even harder.
