Dirt Collector's Edition doesn't exist, yet. As of right now, there are currently only two versions available for Dirt 5 pre-order, the Standard Edition and the Amplified Edition. The Amplified Edition is $20 more than the base game and offers a wide range of perks.
Dirt Collector's Edition: Is There One?
When you pre-order the Amplified Edition, you will receive three days early access as well as a host of incredible DIRT 5 perks and content, including the Ford F-150 Raptor PreRunner by Deberti Design.
On launch, Amplified Edition players will have three ready-to-race cars in their garage (Ariel Nomad Tactical, Audi TT Safari, VW Beetle Rallycross), three-player sponsors with fresh objectives, rewards and liveries, and content for features yet to be revealed – all exclusive to Amplified Edition, along with boosts to your currency and XP earnings.
After launch, Codemasters are committed to "developing a massive selection of new show-stopping moments, and new ways to truly Let Loose. Amplified Edition players get access to every single post-launch addition to DIRT 5, including a minimum of 12 new cars, 60 new Career events, new player sponsors with fresh rewards and liveries, and more items for features yet to be revealed."
