Swarm Defender
is a classic tower defense game where you have to defend against bugs coming for your facility's on planet!
Build your defenses, upgrade your towers, and figure out the best setup for each map. There are 14 towers to unlock, with 3 different upgrade paths for each one.
You unlock new towers by playing and earn XP to unlock upgrades. Try different tower combinations and upgrade paths to find what works best against the later waves.
There are 4 maps and 4 difficulty levels, so there's plenty to work through as you unlock more of the game. If you get disconnected from host you can rejoin them!
Cloud saves unlocks save between computers.
Planned In near future more maps! More bugs! More towers! Calling in support from the ship
