You can do this online or in local co-op, but there is a trick if you want to do it solo. Press start on a second controller to add another player. Go to the simulator and select Stark HQ 1. Once the map loads, go to the center console and select Next Mission. This counts as 1 map completed in co-op. The game will bring you back to the Sim menu. IMPORTANT! You need to exit out of the Sim menu completely or you'll get stuck having to replay missions. Go back into the simulator and start the process over again. The game will count your current map as completed in co-op too, so you will only need to repeat this process 12 times.

Very Rare
You will need to perform each of the 276 unique fusions for this trophy. Overall progress is under Stats > Fusions. Progress for each individual hero is also kept - 23 fusions for each. A single fusion counts towards both characters. That is, if you are Iron Man and fusion with Captain America, you do not need to play as Captain America and fusion with Iron Man.

Fusions do NOT need to hit or KO an enemy to count. The best place to get these done is in the Basic Combat sim. At the end you will have unlimited fusion stars to work with.

There are flame and gun turrets throughout this simulator mission. Just walk by them. They will do damage to the robot you are escorting, but it's manageable, even on Super Heroic. I used the Natural Forces team for this trophy: Thor, Jean Grey, Storm, and Human Torch. Use this team and 5% of the damage you deal will be returned to you as health.

Ultra Rare
You need to complete this simulator mission with your team consisting of any of the following: Jean Grey, Wolverine, Gambit, Iceman, Storm, Psylocke, Cable, Juggernaut, or Magneto. You should see "X-Men" on the top right corner of your team selection screen. I'd recommend Wolverine, Jean Grey, Magneto, and Iceman.

The mission is to defeat Magneto, and will take place in several phases. The best powers to use are Jean Gray's Pyrokine Blast (r2 square) and Wolverine's Lunging Rage (r2 cross)

Phase 1: Magneto will be by himself. When you get his health down to about 70%, he'll encase himself in an invincible shield and move to the center. Here he'll bring up some missiles to shoot at you, which are easy to dodge. Then he'll spawn two large robots. Defeat these and he'll drop from his shield.
Phase 2: Magneto will attack you again but this time there are little robots attacking you too. This is a good opportunity for a targeted fusion if you have one ready. Jean Grey and Wolverine do a nice one. Keep attacking him until he puts up his force field again. You'll have to fend off 4 large robots this time before Magneto drops down again.
Phase 3: Magneto will spawn lots of little robots to keep you busy. Keep track of him as he runs around on the screen. It's easy to lose him amidst the chaos. A guided fusion could work here to clear out the robots. Once you KO Magneto, the mission is over.

Blows Up Real Nice
Throw all the proximity mines in "Balance."
1.94%
Ultra Rare
During this mission you'll be forced to move left to right to avoid a force field. Your objective is to throw each of the mines that are laid out throughout the level. The first thing you should do is kill your team - they get in the way and may inadvertently trigger a mine. At the start of the level hold l2 and force your team to get killed by the force field. Now, progress through the levels picking up mines with square and throwing them with square . A couple are semi-hidden behind the breakable walls, so pay attention. The trophy will pop before the end of the level.
