For Very Easy:

• It's best to go to the Beswick position and turbo (if available)/mash stingers at the door , in general turbo/mashing is faster than trying to time your shots
• This strategy should be avoided on PS2 and PS3 because of the stinger lag

For European Extreme:

• The order of the chokes should be : 10 chokes then release → 3 chokes then release → 1 choke then release → 1 choke then release → 1 choke then release
• You don't want to choke the Tengu too fast otherwise the skip will not work as you want to keep him alive for as long as possible
