You, the grizzled PC gamer in the corner, you remember diving around with akimbo pistols in that Half-Life mod in The Good Old Days, don't you? No, not Action Half-Life. No, you big silly, not The Opera. You know, The Specialists! Some of the folks behind that side-diving, slow-motion shooter are now working on a free "spiritual successor" mod, Double Action, and want Kickstarter help to finish it faster. You can give an alpha version a go now, too.
