Introduction:
Welcome Mars and the third installment of the Red Faction series and the first to be released on the 360. This game is a somewhat frustrating game to get the full 1000

Step 1: Getting started
First thing, the difficulty matters for nothing in this game. Save yourself a lot of headache and play the campaign on easy. Next thing you'll want to do is get THIS list of radio actions (one's that are not located on your map, you get them called in on a radio in the vehicles) and mark them off as you complete them. This is the biggest problem people have.
Step 2: Playthrough
Once you have your list ready, play through the campaign (on easy) and complete all of the actions (green markers on your map) as you go. As you liberate a sector, you will not have access to finish any left over actions you have missed until the end of the game. You can do this either way – personally, I found it much easier to do them as I go and keep track of which one's I've done. Every time you get a radio action called in, if you can, drop what you are doing and try your best to complete it. If you fail, it will pop up again. Just remember to mark off which one's you complete as you go. If you finish the campaign and you still have not finished all of the radio guerrilla actions, try and use the maps with the link above list to find the spawning point and get it to activate. This is where most people get lost. I spent 15 hours + trying to get 2 missions to spawn because I didn't know where they spawn, so I had to restart the game.
You can run through all of the stories missions (Yellow diamond on your map) pretty fast if you want, you'll just need to lower EDF control as you go to liberate a sector. Once the EDF control is at zero, the sector will be liberated and another one will open up with new actions and story missions. Keep doing this until you have beat the campaign. Try to not mine any ore while playing the game, save this for your clean up and do it all at once.
Step 3: Cleaning up
Once you finish the campaign, go back and finish anything you might have missed, like the pro times for demolition and transporter missions or the 1 billion credits worth of damage if you did not get it during the campaign. This is also your chance to finish any guerrilla actions you may have missed on your first playthough. Remember that the ones you have completed are a dim green on your map and the one you've yet to complete are lit up bright green. Check your progress in the statistics menu. Please refer to the achievement guide for tips and links to videos to help you finish these, especially the pro times.
Now you'll have to go on a collecting spree to mine the ore, collect the radio tags and destroy the propaganda. Use THIS interactive map for collecting all of those. Also remember that you can see ore on your mini map, indicated by a small red dot and radio tags by a blinking green dot. The only other game mode you'll have to play is wrecking ball for 3 achievements as that's not online. Refer to the achievement guide for info and tips on the wrecking ball achievements. Any other achievements you have left over should be fairly straight forward.
Step 4: Online
Almost all of the online achievements can be boosted with 2 people in custom matches. You'll need to get few extra people to boost a few of the bonus xp events for the Mad Genius achievement. The only other 2 achievements that need to be done in ranked matches is the 250 games played/wins. Just keep playing ranked games until you get these done. For Boosting your XP, check out THIS thread for the fastest way. Remember you gain XP in custom matches. Check the achievement trading thread HERE if you need a boosting partner.
Step 5: DLC
If you have the Demons of the Badlands DLC, it's very easy to finish the 10 achievements in 5 or 6 hours. More than half of the points are just story related and can be unlocked within an hour or two. Then a little bit of collecting and some pro times will net you the 250

Conclusion
This game will take a while to finish, but it's definitely worth it. The tricky part is finishing the 104 guerrilla actions. If you've done this, the rest is a piece of cake. Congrats on beating Red Faction Guerrilla!
