PixelJunk Shooter

In order to get this trophy, you must get a gem symbol by every level in episode 2. To get a gem symbol you must collect every gem in that level. Unlike the survivor trophy you do not have to collect every gem in one play-through of the level, you can come back and collect the gems you missed without having to recollect the gems you already got. You do not have to get the gem for collecting every survivor. Here are guides for episode 2's levels:

 

Level 6 - "Cool Down"

 

Level 7 - "Treading Carefully"

 

Level 8 - "Boom Town"

 

Level 9 - "Trespassers Prohibited"

 

Level 10 - "Ice Burn"
