Game Bonuses

Dino Crisis Bonus Outfits
If you beat the game in under 8 hours then you will get new costumes to wear as you play again.

Dino Crisis Fourth Outfit
When you finish the game for first time, Regina will get two new costumes (Battle type, and Army type). If you play through the game twice, you will get a 4th outfit for Regina to wear. It will change her into a cave girl. Almost as though SHE came from the portal. An extra bonus for getting this is that if you CHECK her guns at your EQUIP menu, you will find that they have turned to ancient type weapons. They will still function like normal, though.

Dino Crisis Infinite Grenade Gun Ammo
When you have seen all three endings to Dino Crisis (you must play three separate games from start to finish). Regina not only starts with Grenade Gun in her arsenal, but she also has unlimited ammunition. Jackpot!
