Apex 2013 was the fourth tournament in the Apex tournament series, held by Alex Strife. It was held from January 11-13, 2013. It was the largest Smash 64 tournament with 95 entrants, the second-largest Brawl tournament with 338 entrants, and the third-largest Melee tournament with 336 entrants. Like the preceding Apex tournaments, Apex 2013 had a fair amount of international competition.
The most notable event at this tournament was Salem coming out of nowhere to win Brawl singles using only Zero Suit Samus. Not only had he won one of the largest Brawl tournaments using a character that wasn't top tier, but Salem had not even won any of the New York/New Jersey local tournaments he had attended earlier. The results of this tournament, along with Salem's demonstration of Zero Suit Samus' techniques, caused her to rise up on the next tier list and many players now think she is a top tier. Kikoushi also won the Smash 64 singles tournament, defeating Isai in grand finals, and Armada became the first player to win Apex more than once, winning Melee singles in both Apex 2012 and Apex 2013.

 Melee The Links vs The Stinks crew battle
Before the main exhibition event, a team of seven Links challenged team of six well known low tier mains (joined by "The Final Boss" Kage) to a crew battle. Unfortunately, the Links were utterly outplayed, losing by nine stocks and failing to even get one Link to fight Kage. The battle was streamed by 8WAYRUN and can be viewed here on YouTube.
 Melee USA vs The World crew battle
The main Melee exhibition event of Apex featured a rematch pitting the best Melee players of the United States against the best of the rest of the world. The teams differed slightly from the previous year's crew battle, as The World added the new threats Gucci and Overtriforce. The USA ended up taking the crew battle, overwhelming The World by a large margin. This time the World did not make it to the final member of the USA crew, who remained undecided between Mango and Mew2King. Had The World made to the end however, the final USA player would have likely been Mew2King, given Mango initially refused to play, opting to watch a soccer game before coming back mid-crew battle to coach the USA. The battle was streamed by 8WAYRUN and can be viewed here on YouTube.
 Brawl USA vs The World crew battle
This year, crew battles were extended to Brawl as well, since the Brawl crew battle at the previous year's Apex was cancelled due to time constraints. The World managed to win the crew battle, as Kakera and Ally managed to pull a comeback from the damage done by ESAM and DEHF. It could be said however that the USA did not have the best available towards the end of the fight, as Vinnie opted to drop out of the USA team towards the end of the battle and subsequently mikeHAZE was sent to fight Ally as a substitute. Due to time constraints, the battle was streamed by CLASH Tournaments instead of 8WAYRUN and can be viewed here on YouTube.
