Action

Radial Plus

Radial Plus is a unique little action game that was initially created for the Something Awful Game Dev Challenge. Although it may look like a typical arena shooter there is one cool twist with Radial Plus' gameplay. Instead of directly hitting the enemy to take them out, you would need to find a suitable angle and fire away before you can actually cause damage to the enemy ship. It's amazing how one little shift in game rules can affect the entire game. This minor change in gameplay results in a creative and challenging game that requires you to think ahead of where your next shot will go. Apart from this, the game is quite enthralling both in sound as well as in graphics. It's this little detail that makes this game worthy of your time.

Fun game that's well worth several hours of your day.

Dash and the Stolen Treasure

Dash and the Stolen Treasure is a cool platformer made by 5 university students, namely, Joel Roset, Josep Catala, Marc Veiga, Marcos Herraiz and Carles Fernandez. All of them are from Spain. Dash and the Stolen Treasure contains fun gameplay and simple yet entertaining game design. Because of this, it's hard not to compare it to another classic platformer, Crash Bandicoot. Instead of a sly bandicoot though, you get to play, Dash, a pirate who is afraid of the water for some reason. Even though he's just a kid, he seems to have collected all sorts of treasure with him. Unfortunately, his treasure gets stolen by a nasty gang, the Blind Shark Pirates! Our hero then sets off on an adventure to recover his lost treasures, collect coins and exact his revenge.

Robotz DX

Combine old school graphics and some basic shooter gameplay and you get a retro looking shooter game in the form of Robotz DX. True to most retro shooter games, this one is incredibly difficult to master. All 30 levels will give you a good run for your money as you go through each stage. Initially based on an Atari game, Robotz; this game is new and improved yet retains the old school touch quite awesomely. Remade by Josh Monkman, the game beautifully captures the feel and gameplay of the original. Retaining some of the essential elements while adding a more updated look to capture the hearts of modern gamers. It's no joke that the game is difficult to beat so gather up patience and a lot of free time before diving in.

Nezumiman

Nezumiman is a parody/tribute to the NES game, Mega Man. This cool 2d shooter platformer lets you play as a rat that can do almost anything Megaman can do (including the infamous sliding maneuver that became prominent since Mega Man 3.) The game is quite simple to play unlike Mega Man, but it is fun. Your goal is to defeat the evil, Dr. Gyoniku and a his gang of evil rat-like creatures. There are 8 levels in total and you have to beat every single boss in the level to advance. Almost every single aspect is similar to the blue robot series, the only marked difference is the graphics and instead of fighting big bad weird robots, you just fight off weird animals. Pretty cool game that's worth your time.

Privates

Rated 14+, Privates, is a Zombie Cow Studios shooter game developed and released last August 2010. In the game, you lead a bunch of marines down, er, private parts to eradicate traces of sexual diseases. If you find battling chlamydia and herpes down the fallopian tube as interesting, then read on. The game is an unusual take on biology class, that's for sure. The game was rumored to be released on Xbox Live Indiegames, however, a spokesperson for Xbox has confirmed that they haven't received the submission yet. If reports online are to be believed about the content, he added, that it would probably not make the guidelines they have for sexual and explicit content in their games. Well, Xbox or no Xbox, at least you can enjoy this game for free download. Happy hunting!
