In case the banner image and headline weren't a giveaway, 2K Games is throwing a sale on some of their biggest titles in celebration of Halloween. A "spooky" sale. The excellent iOS port of XCOM was half-off earlier this month, but in case you missed it, it's back on sale for $9.99 so that's one you're going to want to jump on. Also NBA 2K14, which just launched at the end of September, is on sale for the first time ever. The full list is below, and I'd imagine we'll be seeing plenty more sales today and throughout the weekend due to Halloween, so keep an eye out.
