It's very clear that the primary challenge that the developers of Agent Under Fire wanted the player to partake in was obtaining high scores. You need high scores to unlock single and multiplayer rewards and your highest scores are saved and displayed under each mission. Naturally, the beginnings of AUF's competitive scene revolved around getting the highest scores, not the fastest completion times. For this reason, the High Score category has been added to the Individual Level page. Along with being a lot of fun this category will also perhaps be the most accessible one for players of all skill levels since speed and advanced tech comes far secondary to simply scoring high.
