Blood Omen 2 (PS2)

Unlock cheat mode:
At the main menu, push L1, R1, L2, R2, Square, Circle, Triangle. Begin a new game to start with Soul Reaver and Iron Armor.

Draw weapon during a jump attack:
During your jump attack, hold L2 then select "Berserk" Release L2 and hold R1. Kain should draw his weapon and hit them with it.

Sneaking up on enemies:
While playing the game hold L2 to be able to creep up on enemies and attack them. Be careful, as at times enemies may be blocking because they may have seen you. This does work on end Bosses.

Wharves: Jumping to Rune Knights:
Around the middle of the Wharves chapter is a place where you have to constantly jump across a river with one Rune Knight in each area you jump to. Before you jump, hit the Rune Knight twice with Telekinesis. When you jump, try to make the jump indicator red so that you hit the Rune Knight. While he is on the ground, press R1 to draw your weapons or get your claws out. Immediately when he stands, start attacking and catch him off guard. Two hits should be required with bare claws and only one hit with some sort of weapon.
