Battle Games
Resident Evil Classic
Only the Sega Saturn version of Classic features this particular battle game, which is (in a sense) kind of similar to the later CV battle game. A huge thanks to Linda for the info (and ranking picture) on this battle game :)
Objective: Kill all the enemies in each room before being warped to the next. At the end of each level there's a boss to face. You must first pick out your weapons from the save room you start in (you won't be able to return), so choose wisely.
Weapons/Items: Knife, Colt Python, Shotgun, Beretta
Items (in-game): Red, Blue, Green Herbs, Ammo for the above guns.
Enemies: Zombies (including Wesker), dogs, Yawn, Plant 42, Giant Spider, Tyrant.
Resident Evil 2
To play as Chris in Extreme Battle Mode you must first beat Level 1 and Level 2 (with any character). He will then be unlocked.
Objective: Make your way from Birkin's underground labs to the R.P.D. and disarm four antivirus bombs. You will find the bombs in; the S.T.A.R.S. Office, Ben's Cellblock, Chief Iron's Sideroom, Marvin's Room, RPD Backdoor (where the Valve Handle is in the A Scenario) and the Meeting Room (where the Red Jewel is behind the fireplace). You do have limited ammo, so use it wisely (in both what you use and who you use it against).
Weapons/Items: Beretta-M92FS, Remington M1100, Rocket Launcher, Ink Ribbon, First Aid Spray
Items (in-game): Herbs, sprays.
Enemies: The whole gamut. Zombies, dogs, etc etc, even Mr X.
Resident Evil: Code Veronica (X)
Chris is one of the two (possibly three) already available characters open when you complete CV and unlock the Battle Game. Once you complete Chris' level you will unlock Wesker for use.
Objective: It's fairly simple, run from room to room, clearing them of all enemies. The rooms aren't in the same order as the regular game, they can lead anywhere. At the end you will be forced to fight Alexia, once you beat her, the battle game is complete. Being that the weapons are unlimited ammo, it's best (and more fun ;)) to use the Magnum. Particularly wait till zombies get fairly close to get the lovely *twack* sound of their head exploding. The faster you complete the game, the better ranking you'll receive.
Weapons/Items: Combat knife, Magnum, Shotgun, Shotgun Shells, Mixed Herbs (2)
Items (in-game): Crap load of herbs, first aid sprays.
Enemies: Zombies, Hunters, Sweepers, Bandersnatches, Alexia Form 2, Alexia Form 3
Bonus Features: Press X at the Tiger Bust (in the room modelled after the Statue Room from Resident Evil). Chris will lean down, stick his hand in the tiger's mouth and then get stuck, struggling to pull himself free.
In the room with the vending machine, choose the grey door to the right (leads to the save room in the regular game). Walk to the slot machine closest to camera and Chris will pull and shake it, revealing a first aid spray hidden inside.
In the locker room, kill all the Hunters and then run back to the cracked mirror. Press X and Chris will clean and preen himself in front of it.
