This item was awarded to players who first played Team Fortress 2 from 00:00 September 17, 2007 (UTC) to 23:59 October 9, 2007 (UTC), the pre-game release beta-testing phase.

The date on Robin Walker's Primeval Warrior is dated August 23, 1998. This is the 2nd birthday of the original Team Fortress mod for Quake, and not Robin's hire date as previously speculated. The date is shown as 1 day prior to the correct birthday due to GMT to CDT conversion. Interestingly enough, while this is not Robin's date of hire at Valve, it is one day short of 2 years from it.
