The Adventures of Tintin: The Game

SWORD: Dispatch as many pirates as possible within the given time
This challenge is not hard. Spam your attack and make good use of to parry attacks. There are only a few enemies that you need to block (the cook, the twins, the machete man) - as long as you block them and spam your attacks you should be good.

Additional tips by Novatic.

In the SWORD challenges everything is done with only 2 controls:
-Attacking: Going up and down with the left stick is the basic fighting style.
-Defending: Always use and change your blade with the left stick depending on how they attack. If they come from above move your blade horizontally. If they come from the side move your blade vertically.
-Countering: If you have successfully defended against an enemy, quickly attack. This is only necessary against enemies that block your attacks. If you have 2 blocking enemies wait for them to attack at the same time, block it and counter them both. Else one of them will just block you.

-Once you know this, sword fighting will be easy and the Untouchable trophy will follow quickly

PLANE:

• Take all photos as quickly as possible. For this challenge, you need to fly through circles; for the higher difficulties you must make good use of the boost. Don't spam it, press when the gauge is near the end to refill it quickly and re-use it. Do not use your boost in sharp turns.
• Collect as many flags as possible within the given time. These challenges are easiest, you just need to fly straight to the flags making good use of your boost. Don't waste your time chasing planes. Make sure to have good timing when using your boost.
• Neutralize as many planes as possible within the given time. The key here is to shoot planes as fast as possible because the number of planes is scripted. Don't fly around in circles looking for planes, you would lose too much time. Planes will come for you.

SIDECAR:

• Win the race. This is a time trial. To be fast always use when you just to have a boost. The time trials are not hard as long as you drive without crashing everywhere.
• Follow and neutralize the lorry within the given time. Very easy, use to use the boost, try to be near the lorry as fast as possible.
• Fire and neutralize as many enemies as possible in time. This is a shooting range, make sure to have a good aim, take down every motorcycle you see. As soon as there is a lorry or a chopper, focus on it and you should be good.
