Prior to being picked up by Jagex and released to a wider audience on Steam, Ace of Spades had an alpha build that was available as a free download. While both versions carry the same name, it was the earlier Ace of Spades with its trench warfare that players seemed to prefer.

This content is supposed to drop today, so if you happen to own AoS already, perhaps it'll be worth it to check back in. I'm somewhat worried that fans of the alpha will feel this isn't enough, since that's how these situations have gone down in the past despite best efforts, but I do love that a) they're trying and b) it's free.
