To get all the shop items you must work for both and finsh everything for them before beating the mission "Battle for carucas v.s (allies or china).if you beat the mission before you do this then you can't get them.if you do this for all the contacts you will also get the acheviment :Digital man:.

There is an easy way to get as many airstrikes as you want.(and it's free!)Just get all of the nearest fuel tanks, Money wads, and air strikes as you can, save and restart.All of the resources you picked up are back, and you have the ones you collected earlier! Happy spending and exploding!

Find a chinese tank and if ther is a person driving it,slowly walk towards it. The tank should retreat! P.S. It wont work if the chinese are hostile. So have fun

From the PMC go to the UP HQ. When the gates open walk strait on the left side of the road, untill you get to the wall. Turn around and you should see a red box (if you havent got it yet) walk up to it and press Y. Collect more spare parts so that Eva (the mechanic you hire) can make custom vehicles that she sells to you.

More of a glitch than a hint really but, if you did not notice, when you first recruit Ewan he mentions that his last name is Devlin ;however when he delivers a helicopter to you in the field use your binoculars and you will discover that according the the binoculars he is in fact Ewan Garret. So I will leave you with the evidence and let you decide Garret or Devlin?

To get the nuke, beat all of the contracts from either one of the two final factions to play the final mission. After the final contract is beaten, Eva in the PMC will sell you the nukes for about one million dollars per nuke. Make sure you are stocked up on fuel because nukes cost about five hundred fuel per bombing.
