An Apex Legends player utilized the new volcanic vents in Capitol City to escape the enemy, even when they were knocked. While the giant crater in the ground looks dangerous, you won't instantly die if you fall in it or use it to escape. Instead, you'll take some damage, and fly back out the other side.
It's perfect way to escape or avoid the bridges and chokepoints.
Redditor ____Maximus____ posted the clip of a Revenant escaping with their life by crawling into the vent. With a gold knockdown shield, they would be able to resurrect if they could get away from the enemy squad. Utilizing the volcanic pressure, they float away to the far side of the crevice and pops the knockdown shield ability.
Apex Legends introduced new map changes during the launch of Season 4 and while most of the map looks the same, Respawn did split Capitol City in half. It causes the city to be less cluttered and provided some fun gameplay around a giant chasm in the earth. Just make sure to use the vents to your advantage.
