Do rockstar games allow cross game achievements?

The only verified information available refers to the 2005 beat 'em up video game The Warriors, developed by Rockstar Toronto and published by Rockstar Games. This source describes the game's plot, release dates, and platforms, but it does not mention an achievement system or any cross‑game functionality. Because the provided evidence does not address achievements, it cannot confirm whether Rockstar Games allows achievements to carry over between titles. Consequently, based on the current data, we cannot assert that cross‑game achievements exist for Rockstar Games. Further research or official statements from Rockstar would be required to answer this question definitively.
