Arcen Games offers the first beta release of Children Of Neinzul, an upcoming "micro-expansion" for AI Wars, their sci-fi RTS game. The beta patch also includes some new features for the original game, and the micro-expansion is also now available for preorder for $3.99 USD. In a generous move, they are pledging all the profits from this to the Child's Play charity: "When you purchase AI War: Children Of Neinzul, you're not only getting an exciting new expansion, you're also supporting an important cause. Arcen Games has partnered with the Child's Play charity, pledging 100% of the profits from sale of Children of Neinzul (any taxes and distributor fees) to helping sick kids in need."
