As written by SEGA’s senior localization producer Patrick Riley:
1. Always remember that Jack can dodge enemy attacks by shaking the nunchuk. Not only will Jack avoid taking damage that way, but if timed correctly, Jack will instead dive to the side and roll behind the enemy setting Jack up in a good position to counter-attack.
2. To score lots of points, find an area with a lot of environmental kill objects placed close together. Move an exploding barrel to that area, and find that level’s lure object. Then get a bunch of enemies to follow you back to the area where you dropped the exploding barrel, and throw the lure object. And when the enemies gather around the lure object, throw the exploding barrel at them.
3. If you are looking to earn the most points possible, always complete the DeathWatch Challenges.
4. If the bat is available in the level, save it for the boss fight.
5. Try to use environmental kills that will let you recycle the object that you shoved into the enemy. Stuff like the dumpsters or the electrical signs instead of throwing people into the out-of-play area kill spots (the river in Downtown or out of the dining room window in Courtyard).
6. When trying to complete any of the time-sensitive DeathWatch Challenges, skip any Blood Bath Challenges to save time.
7. Always look inside crates and other objects. You won’t find anything solid in there, but plenty of other goodies await you!
8. Happy Onions refill the health and chainsaw gauge. They also keep Jack happy. And when he’s happy, you’re happy.
9. The more the merrier! Be sure to kill several enemies at once to obtain a higher score. This is bound to be quoted on the 10 o’clock news somewhere…
10. You can pierce an enemy with up to five different caution signs. Some people call it excessive. Jack calls it a work of art.
