Marvel Ultimate Alliance 2

There are 7 total goals for this achievement. They can be done at any time during the story or during simulator missions. They are as follows:

• 20 Car Explosion Hits: Blow up a car near a group of enemies (cumulative).
• 5-Chain Reaction: Find any group of barrels, cars or munitions and use a projectile character to shoot them. You can try the Grim Reaper fight in the Factory level for a good chance at this, or with the barrels along the wall in the Black Widow fight. You need to only shoot one barrel which will then cause four other to explode.
• 20 Robots Killed with Own Grenades: This is actually a bit misleading as you can kill ANY type of enemy with a robot grenade to count for this. So when you see the big mechs in Act 2 that spit out grenades, pick them up and throw them at the other enemies. Also can be done in the Heavy Metal sim.
• Knock Down 5 Enemies with 1 Object: Using a stronger character (Hulk or Thing for instance) grab a big object like a bus and throw it toward a larger group of enemies.
• 20 Melee-to-Power Chains: After using a basic attack with , quickly hit and pick any of the four face buttons to use a power move as a combo.
• 20 Enemies Hit with Fire, Cold AND Electric: The easiest way to do this is to equip team boosts that add each of those three elements to your melee attacks. Otherwise, Nick Fury has all three attack types, or you can use a team of Human Torch, Storm and Iceman. One enemy has to be hit with all three types before dying for it to count.
• 50 Enemies Thrown From High: The three best places for this are Convoy Strike, Guard Duty and Tribal City. Just throw someone off a high ledge or bridge.

• 20 Car Explosion Hits: Blow up a car near a group of enemies.
• 5-Chain Reaction: Find any group of barrels, cars or munitions and use a projectile character to shoot them. You can try the Grim Reaper fight in the Factory level for a good chance at this, or with the barrels along the wall in the Black Widow fight. Make sure to only shoot ONE of the items, which should then explode and cause all the others to blow up. If you shoot them all, they'll all blow up at the same time which will not work.
• 20 Robots Killed with Own Grenades: This is actually a bit misleading as you can kill ANY robot with a robot grenade to count for this. So when you see the big mechs in Act 2 that spit out grenades, pick them up and throw them at the smaller robots. You can also work on this in the Heavy Metal sim mission.
• Knock Down 5 Enemies with 1 Object: Using a stronger character (Hulk or Thing for instance) grab a big object like a bus and throw it toward a large group of enemies.
• 20 Melee-to-Power Chains: After using any melee attack, quickly use a power attack (right trigger+ with Thor is a quick one) to get the combo.
• 20 Enemies Hit with Fire, Cold AND Electric: The easiest way to do this is to equip team boosts that add each of those three elements to your melee attacks. Otherwise, Nick Fury has all three attack types, or you can use a team of Human Torch, Storm and Iceman. One enemy has to be hit with all three types before dying for it to count, so the team boosts option is by far the best.
• 50 Enemies Thrown From High: The three best places for this are Convoy Strike, Guard Duty and Tribal City. Just throw someone off a high ledge or bridge.
