Easy escape
When you are cornered or cannot outrun a Zoid, just use a Speed Booster. Another thing you can use is a shield. If you use one, speed on a Rev Raptor is recommended. You will have a very strong Zoid that can defeat lots of opponents easily.

Cargo mission
On the mission where you have to protect the cargo, use the Cannon Tortoise's 8 Shell launcher for maximum destruction. Note: Use it at long range.

Recommended Zoid
When you do tournament or mission and can buy a Rev Raptor (sell the twp weak ones), use the two pointy things at all times. You can use it unlimited times and it does good damage. It is possible to defeat a Fuzor Dragon without getting hurt by doing this.

Shield Liger DCS-J
Start the game with a save game file from the Japanese version of Zoids Versus on your memory card to have the Shield Liger DCS-J immediately available at the store.
