Portals through which someone can penetrate from another world must be securely sealed, but anything can happen, so there are always so-called guards near them who stop single attempts at penetration from both sides. However, in Grukkle Onslaught everything is much more serious and a couple of guards are not enough here. We will have to organize a serious defense against the breakthrough of an entire army of monsters. Place towers in specially marked places. You will have a choice of where to install the tower and which one. At first, a lot will depend on the availability of coins. But the more enemies you destroy, the more coins you will receive in Grukkle Onslaught.
