TL;DR Summary

GTA Online is paying out up to GTA$2.5 million during the Community Series Showcase from March 12 to April 1, with a GTA$1,000,000 login bonus and weekly GTA$500,000 bonuses for finishing five Community Series jobs in each of the three weeks. The event also rotates free Special Vehicles through Warstock Cache and Carry and gives out an LSIA Vehicle Warehouse, but claiming that warehouse requires CEO status and an Executive Office. Weekly race and Deathmatch challenges unlock cosmetic items, while featured Community Series jobs and several business activities get boosted payouts.

Rockstar Games is running the Community Series Showcase from March 12 through April 1, which is a three-week event built around player-created jobs and modes, with a stack of free rewards attached if you put in the time.

The headline number is GTA$1,000,000 just for logging in at any point before April 1. No conditions beyond showing up. On top of that, jumping into any Community Series job earns 3X GTA$ and RP. Complete five Community Series jobs in a single week and you get a GTA$500,000 bonus. Do that across all three weeks, and that's another GTA$1,500,000 in your pocket, or GTA$2,500,000 total if you count the login bonus.

Each week has a theme. The first week spotlights both Combat and Race modes, with a featured Transform Race called Face to Face Colors by Chris-Himself. Week two goes full combat with rocket launchers, fast vehicles, and chaos. Week three closes out with a race-heavy lineup, including a face-to-face multi-vehicle track called CARA A CARA RAPIDISIMO 2. The featured jobs rotate weekly, but you can always find the Community Series through Quick Join on the iFruit or the Legion Square blip.

If you want the cosmetic rewards, there are weekly challenges to track. Win three races March 12-18, win three Deathmatches March 19-25, then win three more races March 26-April 1. Finish all three, and you unlock the Community Collection that includes a Homies Sharp Tee, a Benny's Fitted Cap, and the Knuckleduster livery for the HVY Nightshark. Progress can be checked in the Interaction Menu.
