Alien Breed 3: Descent Trophies
Can't Get Enough
Complete the prologue, all single player, co-op assault and survivor maps.

You must play all of the following:

Prologue

Single Player

Subversion
Re-entry
Determination
Vengeance
Resolution

Co-Op Assault

Mainframe
Systems
Cargo Hold

Survivor Mode

Survival - Pressure
Survival - Resist
Survival - Onslaught

Prologue can be selected from Free Play. You can do Co-Op Assault locally with two players or through the PSN. You must finish the assault map for it to count towards the total. For Survival Mode, you can choose to play the maps by yourself or through the PSN, it counts either way. Finish off Wave 1 at least in order for it to count, just to be safe.

Note: If you're having trouble unlocking this trophy, try playing through Survivor, Prologue, and Co-op Assault all in one sitting. Despite placing in the leaderboards, sometimes the game won't recognize that you have completed them.

Play on each map once, and the trophy will unlock.
