GeoDefense Swarm Medium Level 3 Walkthrough and Solution
Geo Defense Swarm Medium Level 3 is a fairly short level with only 13 waves. There are also 2 creep entrances and 2 exits. If players start by trying to build a maze around this setup, they would probably fail. There are just too many creeps coming in from different directions.
The easiest way to beat this level is by building two laser towers placed directly after the speeding grids as shown in the wave 1 image below. Afterwards, upgrade them and build a stun tower and a missle tower near the center to slow and blast those creeps for the 13 short waves!
