《Ace of Spades》（缩写：AOS；翻译名称：黑桃A、黑桃As），是一款沙盒建造射击游戏，玩家可以在一个三维世界里用各种方块建造建筑物抵御敌方攻击，也可以攻击对方。此游戏由Ben Aksoy独立开发。《Ace of Spades》基于网上服务器平台。游戏队伍分为两队，蓝队和绿队，玩家可以选择加入蓝队和绿队，再选择步枪、冲锋枪、散弹枪。每名玩家有100生命值，生命值少于100时，可以到补给站补生命值。当玩家死亡时，需要等候时间重新游戏。最近Steam被买下，推出全新版本AOS。由于游戏地图与《Minecraft》相似，所以又被称为“枪战版Minecraft”。
it’s awesome, free and runs on any PC. It’s the best bits of Minecraft crossed with the fast-paced shooter gameplay of Team Fortress.
