Too many of these are being released. I can hardly keep up. I've got all of the ones mentioned above already. Dungeon Defenders has several dlcs to add if you really get into the game.
Oddly I'd just booted up Brainpipe for the first time in ages just before I read your post though it said it was unavailable via Steam so have just redownloaded it.
Not sure whether I'll bother with this one unless they add something else later. :)
You can find the deal HERE

Dungeon Defenders:
Dungeon Defenders is a Tower Defense Action-RPG where you must save the land of Etheria from an Ancient Evil! Create a hero from one of four distinct classes to fight back wave after wave of enemies by summoning defenses and directly participating in the action-packed combat!
Customize and level your character, forge equipment, gather loot, collect pets and more! Take your hero through multiple difficulty modes and challenge/survival missions to earn more experience & even better treasure. Join your friends with 4-player online and local (splitscreen) co-op to plan your strategies together or compete in PvP Deathmatch.
Key Features
1) ... 4-player Online and Local Co-Op - Team-up with up to 3 friends to defend cooperatively, with character classes that support each other’s strengths and weaknesses. Dynamically combine local (splitscreen) and online players and leave/join any time, so that the game’s always full.
2) ... Tower-Defense Meets Action-RPG - Choose your class, customize your character & equipment, strategically assemble your defenses, and participate directly in action-packed battle to preserve your castle against the invading horde!
3) ... 4 Distinct Character Classes - Each character class has a different skill tree, set of towers, and even basic attacks! You can choose if you want to play stealthy, turn invisible, and plant traps behind enemy lines with the Huntress or go all out, block off choke points, and brutally beat your foes into submission with the Squire!
4) ... Loot and Level-Up - Grab the mounds of money and items that your defeated foes drop and trade them or store them for later use in your Item Box! Getting kills and completing waves earns you experience points, which can be used to upgrade your characters, skills, equipment, and towers on a per-statistic basis. Do you want to enhance Hit Points, Attack Rate, Damage, etc? The choice is yours... Store your massive overflow of money in the 'Mana Bank' and then spend it to improve your equipment or trade with other players. Proudly show off your best equipment in your own 'Adventurer’s Tavern', without fear of item theft!
5) ... Tons of Enemies and Huge Boss Fights - Over 100 simultaneous enemies will attempt to tear through your defenses and gigantic Boss Monsters will appear to rain down havoc upon everyone. Only by employing the most effective defensive strategies, teamwork, and strong characters will you defeat such devilish foes! Many enemy types run the gamut from big dumb Orcs swinging huge axes, to lithe Dark Elves that strike from the shadows, to crazy kamikaze goblins! Can you defeat the epic boss battles and collect the special loot while still defending your crystals?
6) ... Mission & Game Play Variety - Each level has a different visual setting, layout, enemy types, traps, and distinct surprises. To collect all the loot and reach the highest levels you must take your character through 4 difficulty modes, survival missions, challenge maps, and more! Some maps force you to have mobile defenses, guarding a crystal which warps around the map. Others have YOU attacking enemy encampments!
7) ... Collect and Trade Pets Online - A variety of pets exist to assist you in the land of Etheria, each with distinct behaviors. These pets can be leveled-up and customized to match your unique play-style. They can even be traded online with other players!
8 ) ... Secure Trading System - Afraid another player won't live up to their word? Use our secure trading system to trade your precious weapons, armor, and pets with other players online! Watch your name and fame spread online, as people seek out the best pet raisers or item forgers!
9) ... A Mountain of Stats - Every shot you take, kill you make, and defense you build is logged and recorded for posterity. Pore over the voluminous charts and graphs at the end of each session to analyze your team’s performance, quickly review your best statistics for each level, and compare your data online with other players to see who is the greatest hero of all. Furthermore, your Achievements are visible for all to see within your very own Adventurer’s Tavern, and the highest scores for each of your heroes are ranked on the worldwide leaderboards!

Brainpipe: A Plunge to Humanity
Is it an otherworldly mind control device, masquerading as a seemingly quaint computer game?
Is it a gateway to worlds beyond our own, created by eldritch wizardry and invoked by strange creatures hidden away on uncharted islands in the South Pacific?
Perhaps it’s a message from the future, an instruction to mankind to uplift humanity to a higher state of being.
Or maybe it’s just an addictive endurance run game from Digital Eel.
BRAINPIPE is a unique gaming experience. The ultimate objective is to transcend humanity. You do this by navigating the tunnels of your mind, exercising your hand-eye coordination while relishing in the funkadelic sights and sounds of your inner self. Collect the illuminated glyphs while avoiding the nasty obstacles. They may look all nice and shiny, even warm and inviting, but each brush with them brings you one step closer to eternal darkness!
BRAINPIPE is also an easy game to play, hearkening back to the classic arcade games of yesteryear. A one click interface keeps you focused on the action, instead of searching for the right key to press, and is a perfect complement to the soothing audio and visuals.

Containment: The Zombie Puzle:
Containment: The Zombie Puzzler is an action puzzle game like you’ve never seen before. The goal of Containment is to surround zombies with survivors of the same color. But watch out for the zombies—they'll fight back by infecting the survivors in the street. Through the game's pulse-pounding campaign and multiple survival modes, you'll use your wits, items you find you along the way, and even the town around you to contain the zombie outbreak.
Key Features:
1) ... Not a Match 3 In Containment, you don’t match three of anything—you eliminate zombies by surrounding them with survivor tiles.
2) ... These Tiles are Alive Each tile is a fully animated character that interacts not just with its fellow survivors and zombies, but also with the environment.
3) ... Unique Storytelling There's no time for cutscenes or dialog boxes when the undead are trying to eat you—the story of Franklin County and its survivors is told through in-world text as you make your escape through what's left of the city.
4) ... Real-Time/Turn-Based Containment combines the cerebral strategy of a puzzle game with all the real-time action you'd expect from a zombie attack.
5) ... WMD’s Playing the game well rewards you with useful items that you can use against the zombie horde to devastating effect.
6) ... The Environment is Your Friend Franklin itself becomes a weapon as you knock over signs, power up heavy cranes, and roll cars over zombies.
7) ... Boss battles Yeah, that’s right. We even have boss battles. You haven’t seen zombies like these before.

In defiance, you have trained to work for the Good Guys to preserve Freedom by defeating the devious Grid Guardians, exposing the sinister secrets of those evil villains who use it to conspire and oppress!

Weird Worlds: Return to Infinite Space:
Have you ever looked up at the night sky and wished you were up there, exploring the billions and billions of stars?
Weird Worlds: Return to Infinite Space is a grand space opera that will take you from a down and out starship captain to an amazing intergalactic hero whose renown travels light speed ahead of you! Set in a randomly generated universe of endless possibilities, this single-player experience will let you explore new worlds, meet exotic aliens, discover black holes, witness the deaths of stars, encounter drifting space hulks that promise untold riches or untimely death, and much, much more! And all this happens in under thirty minutes or less!
Although quick to play, Weird Worlds boasts a deep, feature-rich system that ensures each session is as fresh as the first play. Players start off with their choice of one of three ships to explore the universe with, each ship completely customizable through the acquisition of new components, either via trade or encounters. The majority of the game takes place turn-based style on the gorgeously rendered star map (always newly generated each game), and uses a simple one-click system that even your grandmother can quickly master. When your starship encounters hostile aliens the action moves to real-time, and while players have dozens of weapons and tactics at their disposal, the combat system manages to provide this great depth while still maintaining the highly intuitive system of play found elsewhere in the game.
And though it would practically take a lifetime sailing amongst the stars to experience everything that Weird Worlds has to offer, the game never has to stop, thanks to the moddability ease. Gamers will find that with a little artistry and virtual elbow-grease they can take Weird Worlds: Return to Infinite Space into an amazing array of new directions, and truly go where no man has gone before!
Weird Worlds: Return to Infinite Space will provide you with countless hours of challenging gameplay, as you create your own tales of daring do and high adventure in the cold reaches of outer space. With scores of weapons, encounters, artifacts, goodies, and mysteries you'll be lured by the siren call of exploration to push yourself further and further with each session. Find out if you have what it takes to be a star-hopping galactic hero in Weird Worlds: Return to Infinite Space!

They have also added Dr Blobs Organism, tohuugh this was made freeware anyway some years back. you can check out the developers site HERE. You can also get Plasma worm from the deelpers site for free as well. both of these games have been posted in the Good Games to Grab project previously.
Dr. Blob's Organism
He's brewing giant protozoans again -they must be destroyed!
Something very strange is going on in Dr. Blob's mystery kitchen. Pulsing emanations spill from the windows at night illuminating the overhanging willows with eerie green light. Unsettling squishy noises, diabolical laughter and the crackling sound of raw electricity pierce the stillness of the after hours frightening passersby and disturbing nearby residents from their sleep.
Rumors of unlabeled crates and canisters being delivered by dark-suited men driving unlicensed black vans even now circulate among local barflies and conspiracy seekers.
What can it mean?
Dr. Blob's Organism is a lightning-fast shooter game where players blast feisty one-celled organisms as they try to escape from a petri dish.
Each level in the game introduces new powerups (like freeze, lightning and multiguns) and special organism abilities (like force field, regeneration and frenzy) to ramp up the fun and increase the challenge throughout the entire game.
