Oh no, the evil Reach are attacking Odym! This doesn’t bode well for Saint Walker. You’d better disable the big bugs’ mothership before you land. Fly circles around the Reach mothership, blasting their fighter ships to smithereens. Collect the power-ups that they drop to gain shields and better weapons.
Defeat the first wave of Reach fighters, and a giant tentacle emerges from the mothership. Collect a missile (destroy enemy fighters to discover them) and press the Interact button to fire it at the tentacle. Hit the tentacle with two missiles to destroy it.
The Reach aren’t done yet! Their second wave of fighters features giant insects that can withstand more damage. Once you’ve cleared them out, another tentacle emerges from the ship. Use more missiles to obliterate the tentacle, and a third wave of baddies arrives. Use missiles to destroy the big worms in this final wave, then blast the last tentacle to cripple the Reach mothership.
