Xmas Bundle" nets its purchasers six games for the price of ... well, a street vendor hot dog -- there's the remastered Blackwell Trilogy (which is technically three games, right?), the Source-powered Dino D-Day, the topical sim The Oil Blue and the effortlessly delightful Eets.
The whole bundle's currently available (at the time of this writing) for $3.80 -- a price which will increase as time goes on, but decrease if purchasers pay more than the minimum amount. Act fast! Or, for our sakes, act charitable.
