The shake glitch in Corneria is performable with only four characters, and there are two different methods of performing the glitch.
Snake uses Cypher to get into the correct place. The only way he can end this is by fast falling or by being attacked by the laser cannons. It is also possible for Snake to go through the ship. It is easiest to do it (and possibly the only way to do it) if he is slowed, whether by 1/2 or 1/4 speed in training mode or slowed down by the Timer. He has to aim to go through the cannon just at the part where the cannons meet the ship. They should go straight up through the cannons like normal, but if they continue holding in towards the ship, it is possible to go right through it and even land back on top. Snake cannot get stuck in the ship, as he just falls out of the ship when he loses his Cypher.
