Batarangs tip
Sent in by Joker
Always go after Batarangs. They kill enemies faster and you can do it from
a safe distance.
Hidden power-ups
Sent in by Joker
In level 4-2 break the rocks to get much needed power-ups like small
heart containers to boost your life meter.
Jack and Joker tip
To make it easier to defeat Jack and Joker, make it up to them
with batarangs. You can kill them relatively fast if you throw them
so that they touch Jack or joker just as they slow down or stop
completely. This does massive damage to your adversaries.
