Extermination
Expert mode:

dog tags and save. Start another game with the yellow
"Rear Of Compound" save file (00:00:00 time). The game
will begin with extra ammunition (500 bullets, 50 shotgun
shells, 30 grenade rounds, 1,000 flame units, and
25 Ultimate Launcher missiles) and extra health items
(20 Recovery Unit A, 5 Recovery Unit B, 5 MTS Vaccine,
5 Booster Shot A and 3 Booster Shot B). However, enemies
will be more difficult in this mode.
Secret mode:
Successfully complete the game by finding all fifteen
dog tags and Roger's knife. After the credits, and the
funny candy girl song, you can save the game. When you
do, you will notice that the save file is yellow and a
star is next to it. When you load this game, it will begin
with 300 bullets, 50 shotgun shells, 99 grenade shells,
1000 flame thrower capacity, and 25 missiles. You will
also start out with an AT-6 Grenade Launcher. This has a
six chamber revolving unit that you can use. You also
get 25 recovery unit type A, 5 type B, 5 MTS vaccines,
5 booster shot type A, and 3 booster shot type B.
However, the enemies take double the hits to kill in this mode.
