Dash Attack - Snake does a somersault forward, and ends up half-crouching at the end.
Down Tilt - Snake is fully prone while crouching, and he sweeps his legs around.
Up Tilt - Snake kicks one leg up vertically.
Forward Tilt - Does a knee-thrust forward with great speed and large range, and if A is pressed again, he will follow-up with an overhead swing of both arms, which has high knockback and an incredibly large range (it has a huge disjointed invisible hitbox like his up tilt).
All - Puts a cardboard box over himself, which is removable. Depending on which button you press, Snake will get in the box in a different position. When he removes it, the enemy receives some damage (if they are in close range). The box can also be picked up and thrown by opponents. This gives 2% damage, making it the second damaging taunt in the Smash series after Luigi's down taunt. If an opponent is in the air and is hit by the box, it will act like a meteor smash and the opponent will go straight downwards.
Smash Taunt - Kneels down and contacts his support team - Colonel Campbell, Otacon, and Mei Ling, and also Slippy Toad (only when in a Brawl with Falco) and Peppy Hare (only when in a Brawl with Krystal) - via his codec. Snake then receives information on one of his opponents; this goes for every fighter in the game, including himself, and with separate conversations for Sheik and Zero Suit Samus. This is possible only on Snake's home stage Shadow Moses Island, and is performed by down taunting extremely quickly. Snake will hold a pose for a few seconds, then a conversation between Snake and his support team will begin. You can do this only once each round and if you are hit while Snake is holding his pose before the conversation starts, it is cancelled. However, you can be hit while the conversation is going, though the conversation ends if Snake is KO'd, which, in a nod to the Metal Gear Solid game over screens, causes the character Snake was talking with to shout "SNAAAAAAAAKE!!". It can be done with any number of other players on the screen, but if there is more than one opponent the game will randomly choose one character to talk about.
