Basically, if a squadmate gets killed but you slip through the enemies' fingers, you can bring your friend back at a Reboot Van by grabbing the Reboot Card that they drop.
Just like in Apex, respawned players won't have any weapons or items when they come back, so you'll need to either protect them as they loot up or you'll need to give them some of the weapons you're now carrying. Players who respawn from the reboot van wont have any items either, so the squad will have to share items or go back to looting to make sure their teammate stays alive the second time around. Additionally, any rebooted squadmates will be unarmed so if you've revived them you'll need to drop some of your weapons to get them back in the action.
If you've played Apex Legends, you might recognise this system. The Island is surely getting more and more interesting as we're cruising throughout Fortnite's Season 8, and the Reboot Vans may be considered for very important and clutch move, leading to a good amount of satisfaction. Reboot Vans work pretty much the same way as Apex Legends' Respawn Beacons do. You can bring eliminated team members back into the game.
This is clear news that the phenomenal early launch success of Apex Legends-which has become a worthy adversary to Fortnite-has definitely caught the eye of Epic.
The vans are few and far between, and can be tricky to access given the shrinking circle of the map. "They really need to do something about this mid to late game intensity".
In February, Epic Games held a Reddit AMA.
You know what they say, "if you can't innovate any more, just copy people".
