If you are getting a bit bored with the conventional play of Grand Theft Auto 5 and GTA Online, then you might be interested in the upcoming Hot-Wheels-esque DLC Tiny Racers, coming on April 25.
There aren't too many details yet, aside from the fact that it is a top-down racer on stunt tracks that give you the feel of an old arcade racer (or the old Spy Hunter cabinet). There are also power ups and it appears highly combative as you try to take out other racers. The mode looks entertaining enough, and it will probably look even better to everyone today, given that it's 4/20 (if you catch my drift).
Rockstar sure did, and is having a little fun with today's date as well. In addition to revealing Tiny Racers, it also announced a 50% off sale on Weed Farm Businesses and Business Upgrades via the Open Road darknet: "All weed sales from your Business will also earn you 50% more profits. And burn out with Green Tire Smoke from LS Customs, also 50% off today." So toke 'em and smoke 'em today in game.
And out of game, of course, if you are into that sort of thing. Rockstar understands.
