If you love arcade-style action, giant insects, and endless explosions, setting up this patch is well worth the effort. If you want to get started with the setup, let me know:

Despite the official Vita release, the PSP English patch remains a landmark in the community's history. It allowed players to experience one of the series' most content-rich entries on its original portable hardware, preserving a piece of EDF history that otherwise would have remained inaccessible to many.

EDF is balanced around replaying missions. If you hit a wall on "Hard" or "Inferno," drop down to "Normal" or "Easy" to farm better weapons and boost your health pool.
