Get ready for non-stop action without the hassle of loading screens and lobbies.
The massive Freemode Events DLC was included by Rockstar in patch 1.29 for GTA 5 and not only added a dozen new activities and other miscellaneous content to the game, but set GTA V up for the next wave of DLC by reworking the foundations of GTA Online. Freemode Events wiped away loading screens, lobbies and menus.
All in all, Freemode Events has added a massive amount of content to GTA Online and it might seem rather daunting at first. Getting the hang of more than a dozen entirely new missions isn't easy.
However, before you jump into any of the new events, make sure that you are fully prepared for the challenge. You'll need to keep your arsenal fully stocked. So make sure you have plenty of heavy ordnance and enough ammo to kill your way to the top. Amidst all the weapons, however, do not forget to fill your pockets with snacks too. You'll also need a wide variety of vehicles to dominate each of the unique events.

Rockstar also suggest teammates share their monetary resources and rewards. Well, good luck with that! In perhaps a more reasonable/achievable tip, you should always stay on target, heed the pop-up tips and tutorials, and set your targeting preferences to avoid pissing off a friend!
Hunt the Beast
Moving in to specifics, here are some tips for Hunt the Beast. The mode sees one player turned into a semi-werewolf, who has to visit landmarks and survive the hunting team. As a hunter, you should try and keep your eyes on the prey as long as possible when you find him. You can do this by expanding your minimap in the display settings. Audio cues also indicate the proximity of the beast, and it is suggested to work as a team and have a chopper pilot serve as a spotter. Pedestrians will be scared of the beast, so fleeing civilians usually mean you're on the right track. Should the beast jump behind the wheel, keep an eye out for a non-NPC driving style.
As for the beast, you should make sure you've lined up your landmarks with the most efficient route. Being part Werewolf, you are faster and stronger, so don't be afraid to face you pursuers if needed. And taking out choppers is a good idea. Just remember to never get cornered!
King of the Castle
Moving on to King of the Castle, the gamemode which has players occupy a fortified building. As long as you control the fort, you'll continuously be rewarded with GTA$ and RP, but the other players will seek to de-throne you, so keep your gun close.
