FAQ
Q: How do unit synergies work in the game?
A: Synergies are all about combining the unique strengths of different Sentinel types to maximize your defensive coverage. For instance, pairing a crowd-control unit to slow down rapid strike fleets with a high-damage blast artillery unit allows you to wipe out entire clusters of enemies before they can breach your planetary shields.
Q: Is there any form of progression that carries over between my runs?
A: Yes, the game features a rewarding meta-progression system that lets you invest resources earned during your runs into permanent upgrades. You can use these to permanently boost your baseline planetary shielding, energy generation, and overall defensive firepower, giving you a better starting point for your next attempt.
Q: How does the game handle enemy wave generation to keep players challenged?
A: Rather than relying on fixed patterns, the game utilizes a dynamic procedural wave generator. This means that with every wave, the alien fleets will feature randomized combinations of heavily armored boss units and fast-moving strike ships, changing their approach vectors and speeds to test your defensive setup.
