In this week's Grand Theft Auto V Online update, extraterrestrial Halloween-themed activities are in full swing. You'll get double payouts from Alien Survivals, Business Battles, and Gruesome Adversary modes.

A new Business Battle event featuring Merryweather agents in Fort Zancudo also takes place this week. Players will need to take out the agents and make off with any alien technology found. Upon winning any Event Business Battle, players will also receive a free Cultstoppers Tee.

If you want more free T-shirts, log in anytime this week and get perks like the Butchery and Other Hobbies Tee, the Knife After Dark Tee, and the Orange Dot Tech Mask. In the Diamond Casino & Resort's Lucky Wheel, a Blazing Death Albany Fränken Stange is up for grabs as the top prize.
