These can happen at any point without notice. The first of the modes is called Jailbreak, and it sets free everyone who was waiting in the Gulag and everyone who was still spectating. “You will get a one-minute notice before a Jailbreak event happens to find additional armor or secure a weapon for your returning teammates. Jailbreak events can occur any time during the middle game of a Battle Royale match, so it may be worth it to spectate, just in case. Be mindful that when a Jailbreak occurs, it’s not just your teammates that are coming back, but tons of additional enemies,” Infinity Ward said in the official patch notes.
The second new in-match event is called Fire Sale. Like its name suggests, this discounts every item in the Buy Station by 80 percent, or gives them away completely free. The Fire Sales only run for 1 minute, so players will likely rush to the Buy Stations, creating a deadly showdown between squads.
Finally, the Supply Choppers event adds a “non-lethal but heavily armored” helicopter to the map. This helicopter has lots of health, so you need to shoot it with a rocket or a lot of weapon ammo to take it down. When the helicopter is destroyed, it will drop “high quality loot,” including three UAVS, two armor boxes and munitions boxes, a gas mask, a grenade launcher, and lots of Cash.
“Supply Choppers leave after a certain period of time, so if you want to take one out start firing right away. Remember, that after taking down a Supply Chopper, you have to collect the loot. Watch out for enemy teams who might try to take you out during the collection or steal your hard-earned rewards,” Infinity Ward said.
The Season 4 update also introduces Captain Price as a new Operator in the new Battle Pass, while three more multiplayer maps are also available. For more, check out the Season 4 patch notes.
