Two words for you this weekend: Wyv and Keep. Well, actually, that "and" should be included, so it's really three words. You don't really have to pay attention to the third word, but it really helps establishing the relationship between the two nouns surrounding it. Stop reading, go play!

Wyv and Keep: The Temple of the Lost Idol (Windows, 31MB, free preview) - The game isn't finished yet, but Wyv and Keep developer A Jolly Corpse has decided to release a free eight level preview of this wonderful co-op experience. Play it with a pal or by yourself, switching between two characters who must cooperate to solve puzzles and make it through each level. It's a lot like the classic The Lost Vikings, which shall always be the marker for sidescrolling action/puzzle games with multiple playable characters, and the artwork and puzzle design are nearly flawless. A great preview of a game that's shaping up to be a must-have once it's finally released!

WG Realms 2: Siege Breaker (Windows, 56MB, free) - Duke Nukem Forever got you down? Longing for some old school-style Duke-like action? WG Realms 2 has that with a total conversion of Duke Nukem 3D. You don't even need the original game to run it, just download and start playing! Duke finds himself transported to a strange fantasy realm where humans are under attack by monsters. Using new weapons and some strange spell-like abilities, Duke decides to help the humans out so he can get back to his own world. Siege Breaker features big environments filled with secrets and a slight medieval/fantasy theme. It's not your usual first person shooting game, for sure, but the level design is good and requires a lot of poking around, just like those lovely old school games of yore. Give Siege Breaker a shot and soak in the retro goodness for all it's worth!

Crab Blaster (Windows, 7MB, free) - An action puzzle hybrid, Crab Blaster is a short game that puts you in a pickle level after level. Not literally, of course. Positioned on one side of the screen, you must make it to the goal on the other side, blasting your way through blocks in the process. You only have a few shots for each block type, though, so you have to conserve ammo and be creative in order to make it through. Simple, but entertaining enough for an afternoon of explosions and arcade-sounding fun!
