Baron Praxis battle
When you first fight the baron in the palace, take out your blaster and fire at him whenever he stops shooting you. When he is in the yellow he will go to another platform. Before you follow him, fill your ammo from the KG crates. Next he will shoot missiles at you. Just dodge and shoot. When he is in the red he will go to a final platform. Once again refil your ammo. Next he will fire tornados at you and charge you. Go onto the higher ledge where only some of the tornados can reach you. Then shoot until he charges at you. Repeat twice. Or you can finish him with a dark blast (dark bomb won't reach him).
Glitch: Tomb of Mar: Peacemaker
Note: This works best with unlimited ammo. Go to the Tomb of Mar and take out your peacemaker. Go down the elevator. Just go out of the elevator and you should be standing on a narrow path. Stay still and rapidly Press R1. You should hear an echo or ringing. Be patient because this takes a lot of shots.
A good way to deliver Eco Ore to Krew
On this mission an easy thing to do is to follow the best road to the icon which is the prt which takes youm into the busy part of the city. While doing this try and take as less damage as possible and when you reach the roadblock go low so your hovering just above the ground and then head to Krews place by going over the water or staying low and taking the walkway.
NEED AMMO? (tip)
Need ammo? Go to a door that takes you into a building or out of the city. Wait there until a Krimzon guard comes near, then kick his ass! if you need it, when he dies he will give you ammo. Pick up the ammo, kill another guard and pick up the new ammo. Keep doing this until there become too many guards to handle, then just run inside the door until it closes. Wait inside for a few seconds and the come back into the city. The Krimzon guards are no longer after you!
