Best Strategies and Ships for the Different Difficulties

Take Armada -> Energy cannon + Projectile cannon -> Few more projectile cannons, or any other stuff you happen to find -> Save up for more ships -> Wreck.

Avoid missiles. They suck - both as weapon to be used, and a weapon playing against. If you see enemy ship cruising far from you, shooting missiles, just jump out and ignore it. It is never worth it.

If you large group of enemies, use distress beacon, and basing on how many wants to move, either move into the spread group, they moved from, or wait, destroy incoming ships, and then move into the sector.
