Taking advantage of the fact that things can orbit in space, “Solar Chaos” has you placing a mixture of orbiting and geo-stationary defence turrets to defend against wave after wave of enemies. The mix of orbiting and geo-stationary turrets makes the game feel fresh enough to justify a download even if you’ve played your share of tower defence games in the past. $2.99 if you end up liking the free trial enough to unlock the full game.
Here’s what the publisher (Solid Roots Ent.) has to say about the game:
“Orbital Tower Defence in Space! Use both Spinning and Stationary Towers to Protect your Solar System as you Defend against waves of Creatures. (15+ Levels)”
