Tip 2 - Guardian Angel

This mission is key to easily completing the game.
Step 1
Do this mission a few times and just run around killing hatians and stealing their guns and money
Step 2
When you have $6000 go to the block of flats with a garage near the Pay&Spray and buy them.
Step 3
Redo the mission and kill Diaz as soon as you get the chance, and also kill the men with him. Now get in his car and drive it to your garage. You may ask why, it is because this car is damage proof, bomb proof and bullet proof. Don't use it until the next hint though.
