This week we have what is perhaps the strangest Weekend Download offering of all time: a sequel to a ten year old game originally packaged with Chex cereal. Yes, it's as odd as it sounds and yes, you have to have some pretty serious nostalgic yearnings to really get into the game. But hey, Chex cereal looks like miniature waffles, so how can that be a bad thing?

Kumoon (Mac/Windows, 6-9MB, free) - A hybrid third-person shooter and physics-based puzzle game, Kumoon puts you in control of a fuzzy chick with an arsenal of weapons at its disposal and one goal in mind: knock down all of the blocks in the room. Bumping a brick will turn it from red to gray, and you must send them all toppling using as few shots as you can. The game is tightly scored and leaves very little room for luck. Much more challenging than it may seem, you'll spend quite a lot of time fine-tuning your shots on some of these stages.

Archibald's Adventures (Mac/Windows, 8MB, demo) - From Rake in the Grass, the studio behind Larva Mortus, comes a title created in the style of Lost Vikings, though with less of a puzzle slant and a greater emphasis on action. You play the young boy Archie who finds himself trapped in a mad scientist's mansion. Skate your way through over two dozen levels in the demo, and the full version scores you well over 100 stages to complete. There's a great variety of puzzles in the game, both easy and tough, and I found the experience remarkably gratifying from beginning to end.

Mission Extreme (Windows, 2MB, free) - A chunky-pixeled run and gun shooter in the vein of the classic Contra series. A terrorist organization has kidnapped 20 hostages, and as a guy with a gun, its your job to rescue them.Use the [x] key to jump and [z] to shoot, the rest is up to your own mad platforming skills.

Chex Quest 3 (Windows, 7.5MB, free) - Yes, you read that right. Chex, as in the cereal, and Quest, as in... well, as in a first person shooter total conversion of Doom. Oh, and "3" as in the third in a series. The original Chex Quest game came packaged with the cereal back in 1997, and a sequel was eventually released. Now, ten years after the first two games had their epic run, the artist of the original game has polished up another installment in the breakfasty saga. Play it for the nostalgia. You know you want to.
