MISSION HANDLER

Rare
It's best to try for "CRASH AND CONQUER" as host and ignore this trophy, as it will unlock whilst you go for that. See my tip for "CRASH AND CONQUER" for more information how to do this.

WEAPONS 101
Get 20 kills with each of the six primary weapons.
16.65%
Rare
This is probably best to do either when you start playing the game, to get a feel for all the weapons and decide which one you like best, or at the end when you're making the final push for experience to get to rank 25. Just kill 20 bots (or real people, but bots are much easier) with each weapon, and you'll unlock this trophy.

GLOBE TROTTER

9.53%
Very Rare
Make an online lobby, deathmatch, friends only, with bots on, one round, and 5 kills, with all maps selected. Once you've played all 4 maps, and their Showdown variants, you'll get this trophy.

ELITE COMMANDO
Reach commando level 15.

Rare
Most likely, you won't have to try for this, as you'll get it whilst going through Boot Camp, and doing the other trophies, but if you want to grind for it, check my "CRASH COMMANDO" tip for the best way to grind for experience.

BOOT CAMP BEAST
Complete all Grunt and Jarhead Boot Camp missions with a Commando Medal score.
17.56%
Rare
The score for the Boot Camp missions is based on how fast you are, so keep replaying the stages until you can do them fast enough to get the Commando Medal. Most are very easy to get the Commando Medal in. You'll get a good amount of experience for doing this too. Keep going through the missions until you've beaten them all with a Medal score, and the trophy will unlock.

CRASH AND CONQUER
Win 20 online games.
8.02%
Very Rare
Host an Objectives game with a two player limit short time limit, and bots off, friends only. Have a friend join, start the game, and then have them leave. Now, you're free to do all the objectives, netting you "DEMOLITION EXPERT" and "HACKER". On your first match, you'll get "FIRST MISSION" if you don't have it already. Before you're finished getting twenty wins, you should unlock "MISSION HANDLER" too, and if you set the maps to rotate, you might get "GLOBE TROTTER". If you get any power-ups, activate them, and if you can get three in a match, it will get you closer to "SURVIVAL OF THE FITTEST" too.

SURVIVAL OF THE FITTEST
Have all three survival bonuses activated at the same time in an online game 10 times.
12.42%
Rare
You can do this in an online, friends only match filled with bots, and it's probably easiest to do it there. Stay alive until you have all three power-ups, then allow yourself to be killed and repeat. You should get the trophy fairly quickly this way.

BIG BLUNT OBJECT
Kill 100 human opponents by running over them using a vehicle. You need the Heist Map Pack to unlock it.
1.54%
Ultra Rare
This is by far easiest to boost with two people. Get in a buggy or tank and drive next to your partner's spawn point. Run them over, back up a little and wait for them to spawn again and stop blinking, then kill them again. Do this 100 times until the trophy unlocks.

PLASTIC PUNISH
Destroy 50 vehicles detonating an attached C4 explosive. The vehicle has to be occupied by an enemy to be counted! You need the Heist Map Pack to unlock it.
1.56%
Ultra Rare
This is possible but time consuming to do in random games with bots, so I recommend boosting it with two people. Have your opponent get in a buggy and stick C4 to it, then trigger it so the vehicle blows up and they die. This must be done 50 times, so it's still quite time consuming.

MR SWEEPER
Destroy 20 enemy mines in the same round using the CAB primary weapon. You need the Heist Map Pack to unlock it.
1.86%
Ultra Rare
This is easiest by far to boost with two people. Have your partner select mines as their explosive, and you select the CAB as your primary weapon. Have them lay down all their mines and retreat to find more explosives ammo, and then whilst they're gone, shoot their mines with the CAB to detonate them. Do this for 20 mines, and the trophy will unlock.
By Shmenon-Pie on October 1st, 2011
UNSUNG HERO
Restore a total of 3000 health points by using the CAB on hurt team mates. You need the Heist Map Pack to unlock it.
1.67%
Ultra Rare
This is possible to in online games filled with bots, as real people tend to use the sniper rifle which makes healing somewhat hard, but it's easiest to boost with a group of three people. Two should be on one team, and one on the other. You want to be on the team with two people on when getting this trophy. Have the player on the other team shoot your teammate continuously whilst you heal them with the CAB. They will never die as long as you both maintain constant fire. Once you're out of ammo, both go and find more, then return. Do this until the trophy unlocks.

ROBBER
Kill a total of 50 opponents while they are carrying cash in the Heist game mode. You need the Heist Map Pack to unlock it.
1.99%
Ultra Rare
It's best to boost this with two people. Have your partner take the cash to right next to their spawn point, and then kill them. Once they spawn, they can pick up the cash and you can kill them again very quickly. Do this 50 times, it should be possible to do in a 10 to 15 minute long match.
By Shmenon-Pie on October 1st, 2011
BREAD WINNER
Deposit a total of 20 bags of cash in the safe in the Heist game mode. You need the Heist Map Pack to unlock it.
2.35%
Ultra Rare
Either you can wait for a heist server to have you as the only person in it, either through joining one randomly and waiting, or just by having a friend join in a lobby, starting a match then your friend leaving, but once you're the only person, you can very easily get 20 bags of cash. Needless to say, it's best if bots are off when you try this.

TANK SPANKER
Destroy 20 tanks while driving a rail buggy. The tank has to be occupied by an enemy to be counted! You need the Heist Map Pack to unlock it.
1.58%
Ultra Rare
This is easiest done when boosted by two people. You should find a rail buggy and go close to a tank spawn point. The other player should get in the tank and allow you to destroy it with the rail buggy's machine gun. Do this twenty times.

MULTIKILL MADNESS
Score a multikill combo (X4) against human players using the explosives, the primary weapon and the death spin in the same combo! You need the Heist Map Pack to unlock it.
1.22%
Ultra Rare
As this trophy stipulates it must be against human players, it's best to boost this, and probably "SHOOT'EM UP" whilst you're all assembled. You need a group of five people, and you should pick the Sniper as your main weapon and the Mine as your explosive. Get the death spin power up by killing the other players a few times. Now, lay a mine down to your side, a decent distance away but still on screen, and have one person stand close to it, and the other three stand close to you, but away from the mine's blast. Have the mine player run into the mine, getting the first kill, snipe the first of the other three players straight away, getting the second, and death spin the other two, getting the third and fourth.
By Shmenon-Pie on October 1st, 2011
MASTER SPINNER
Destroy 3 vehicles using the death spin without dying. Stay alive for 3 seconds after a successful vehicle kill for it to count. The vehicle also has to be occupied by an enemy! You need the Heist Map Pack to unlock it.
1.58%
Ultra Rare
Two people are needed to boost this. You should kill your partner until you have the death spin, then your partner should find a vehicle and park on a rail diagonal / vertical rail where its underside is exposed. Make sure your partner then knows not to move at all. Death spin into the underside of the car until it explodes. You will likely need to fill up on health between each of the three times you do this. Once you've done it three times, the trophy will unlock.
By Shmenon-Pie on October 1st, 2011
SHOOT'EM UP
Score a multikill combo (X4) while using the stationary gun. You need the Heist Map Pack to unlock it.
2.22%
Ultra Rare
It's easiest to get a group of five people together to boost this trophy. Have the other four of them stand opposite the stationary gun, and fire at them in quick succession until you've killed them all, and you should get a multikill combo.

Alternatively, if you lurk around the stationary gun with bots set to all 12, and their battle moves to opposite the stationary gun, quickly try and pick four of them off to get this trophy. This requires quite a bit of luck, for four bots to appear in the right area at once, however, so it's easiest to boost.
