Suggestions in an update: Recommendation: Electroslow should be able to stun aliens for about 3 seconds at lvl.4 and 5 seconds at lvl.5/Muscle Melter/ Max. Lvl Second Recommendation: Minigun tower that shoots extremely fast with moderate damage on ground and air targets (it would be better if you could make it free too) Third suggestion: EMP tower that can confuse aliens into going random directions for a period of time Fourth suggestion: Massive nuke tower that kills all aliens on the map on any round and the tower costs 800(the aliens still spawn after the nuke goes off) Last request: Biological tower that infects nearby aliens and causes damage over time !!!Please make these free of charge!!!
