Personally, not really worth the trouble IMO. But I’m playing the PS2 version so you can guess why I’m saying this. Seriously though, considering you get an “infinite health and ammo” code/unlockables and slime proof outfit it’s actually all that. Sure the suite is just a colour swap instead of a real alt. costume, it’s still somewhat fun to have it just for bragging rights =P Getting it is the easy part too if you already found and scanned everything. Just change the diffuculty at the lockers and beat the final boss again, it’s that simple. That’s right, no need to replay the whole game all over again on Gozarian, just use the same data with cheats on and the suite is yours.
You can do the same thing on the Wii version as well.
The word is ‘suit’, a ‘suite’ is either a room, or a collection of furniture.
