清洁任务结束了，队友们把你忘在了原地。现在你被外星人团团围住，它们只想把你撕成碎片，不会给你任何喘息机会。你能做的就是尽量撑下去，能撑多久撑多久。队友也许之后会来帮你，也可能还有别的队员同样被留在了这里。游戏是 2D 像素画面，配上 NES、Famicom 那种芯片音效，还有 Awesome Force 制作的 chiptune 配乐，整体是老式街机的路子，难度偏硬核。
你一共能用到五种武器，主要从 Boss 身上掉落。普通外星人有时也会掉些别的武器，前提是别把它们打得太碎。所以战斗里除了活下来，还得留意地上的掉落物，边打边换枪。分数是重点，超过 1000 分、甚至超过 2000 分都能在排行榜上看到，成就和排行榜都会记录你的成绩，朋友也能看到谁更强。
游戏支持分屏合作，接上 Xbox 手柄就能和朋友同屏开打，两个人一起面对外星人。另外 Steam 的 Remote Play Together 也能让你和朋友远程联机，不用凑在一台机器前。开打前先确认手柄接好、分工明确，撑得越久分数越高。
