General Tips
- Spray'n'Pray, or the uncontrolled, constant burst of fire, is not the name of the game in Xenoraid as your guns will overheat. Control your shots and fire in small bursts.
- As each mission has four ships, and repairing them is much cheaper than buying new ones obviously, you should always revolve them mid-combat when their health gets low.
- When upgrading at first you should focus on one or maximum two ships, max them out and then proceed to upgrading the others.
