One of the most popular free first person shooters out there. Works on almost any platform: PC/Linux/Mac OS. Nice graphics. Created to be the perfect cross-breed of Quake Arena III and Unreal Tournament using retro science fiction for style. In Alien Arena you will find the traditional first person shooter game types as well as Deathball and Cattle Prod (which combine deathmatch with some odd goals to complete). Choose from nine different characters, each with their own benefits and shortcomings. Lots of mods (called mutators) are used to change up the rules -- and add a whole lot of fun.See Videos

After the destruction of Earth by an asteroid, warring human factions struggle for resources (specifically Helium3). This is an excellent combination of 3D first person shooter and real time strategy set in outer space. Two teams with dozens of players per side battle it out over the course of an hour or two. The commander builds bases and sets up mining operations, orders bombing runs, and allocates money. Players can switch between ship types on the fly (and even beefier ships if their commander gives them the cash). New players are encouraged to fly scout ships for a few weeks and lay down sensors to spy on enemy movements or keeping other units repaired that are mining or bombing. Good news for new players: they set up servers specifically for new players so they won’t get taken advantage of by veterans while learning the ropes.See Videos

Andromeda 5 is a spaceship action MMO that can be played in the browser. It features a vast array of customizable ships as well as numerous galaxies to explore; players acquire skills that further make their characters unique. More than 200 missions are available, not to mention the quite intensive PvP where players can participate in free-for-all deathmatches and team games as well. Andromeda 5 sports nice graphics and altogether there’s a surprising amount of content that will keep you busy for a while. The game does, however, fall flat when you consider that Andromeda falls well within the Eve Online-dominated spectrum of MMOs and when you take into account that the cash shop seems to give paying players a very real edge.See Videos

Post World War 4 massively multiplayer RPG with some real time strategy elements. Pick from eight main classes with a diverse choice in subclasses. The game's style is hybrid of fantasy and themepunk design with a generous back story. The Noblian and Floresslah (steampunks and mystics respectively) are at war over control of a mineral called Earthdium to help rebuild their world. What image it should be built in however is a matter of opinion. The strategy mode of the game is called a Unit War using basic real time strategy elements with the addition of the ability for your hero to fight alongside the units you create. Unit Wars offer your character high level items and weapons. Movement is controlled with either the WASD keys or mouse clicks. There are multiple vehicles for each faction that have room for multiple passengers. And if you were curious, yes, you can even engage enemies while aboard the vehicles.See Videos

Astro Lords is an MMORPG/Strategy set in a sci-fi universe. Players control an asteroid, construct and upgrade buildings and fight with others to gain control over the Oort cloud. The game can be played on iOS, Android and desktop devices. Players might be positively appalled by the lack of character customization, but that is more than compensated by the fact that eventually you can move your base, perhaps towards the members of your alliance, or the enemy if you feel you can gain an edge. The combat has players duke it out in turn-based combat with spaceships in the vast void. It takes quite some skill and provides ample entertainment, because the fights involve dodging slow-moving projectiles (there are lasers too!) and hiding behind asteroids. You’ll either hate it or love it, but it must be said it’s highly original. Astro Lords is definitely a promising title, but the strategy elements could very well be executed better. The skill tree, huge as it is, confuses the player, because it inevitably makes you wonder if you’re looking at a spreadsheet. Even though Astro Lords doesn’t push players into buying anything, progress is quicker with pockets full of premium currency.See Videos

Battle Dawn is an MMO strategy game, played in the browser. Players start their colonies on three game worlds – Earth, Mars, or ‘Medieval fantasy’ - and each of them has a number of servers. Battle Dawn plays quite differently from other browser-based games, as the game is round-based. Players must form alliances, rally troops, spy or even nuke their opponents in order to capture the ten relics present on each world map; once it’s done, the server gets reset. The game has a peculiar interface, reminiscent of older games like Deus Ex or Unreal Tournament, rather than strategy MMOs. The soundtrack is awesome, too. Battle Dawn is slow in terms of leveling and upgrading your colony, but those interested in it will lose hours upon hours fighting to take control over their world.See Videos

Battle Dawn Galaxies
Battle Dawn Galaxies is a strategy MMO from the eponymous series, played in the browser. It differs from the other games of the series in that it has a sci-fi angle to it. Players start a colony, covering their station with buildings, making spaceships, and forming alliances as well as conquering other players to gather the relics that are required to win the round. Players will enjoy the easy-going tutorial that does a great job of introducing the basics; the interface looks & feels good, plus the music is nice. Battles take place textually, so that aspect isn’t too well-represented. Diplomacy plays a huge role as well—one player summed up the peak of his learning thus: ‘learn to be vague enough so your words will not be used against you.’ Battle Dawn is somewhat ‘hardcore’ in that it has a loyal community and it can take quite a bit of playing to become competitive. It’s a long-term investment, one you should avoid if you’re not prepared to make the commitment. Battle Dawn Galaxy definitely makes for a welcome addition among strategy MMOs: it boasts a small but vibrant community; the game flows smoothly; the mechanics make it a blast once the end-game approaches. It could, however, look better for this day and age.See Videos

Japanese third person shooter using giant robots (mechs). There are four main types of mechs to choose from which can then be customized with practically limitless feature combinations using 300 assorted upgrade parts. Battle for points to upgrade your mech in missions of conquest, quests for treasure or PVP arena battles with teams of up to thirty players. Even scrap your existing mech and rebuild it. The battles (which make up the core of Cosmic Break) are intense and fun to participate in. Single player is available, too, but coop (also available) is more fun than playing alone. Simplistic anime graphics. If you pardon the graphics, Cosmic Break is a fun game with its own flavor and a gameplay that without a doubt beats most of the similar games out there.See Videos

Empire Universe 3
Empire Universe 3 is a strategy MMO ‘empire building’ game, played in the browser. It boasts 9 classes and an interesting (yet at times confusing) user interface. The game has the main features you’d expect from a game of this caliber: resource management, expansion, forming alliances and so on. Plentiful customization options are available in this game: aside from choosing the race and look of your character, the stat point system allows you to direct your empire towards trade, conquest, reconnaissance, etc. Construction and research times are quite slow – be warned. The sci-fi lore is well-written, but the quests are uneventful. The community seems quite helpful, but there are not that many players online. On the flip side, Empire Universe 3 doesn’t require a huge daily time investment, and, as the game is largely text-based, you can become the grand schemer you always were destined to be, finding your way to victory through sheer brain power.See Videos

Epic Duel (ED) is a turn-based dueling game where you join one of two factions on planet Delta V and become a Tech Mage, a Bounty Hunter or a Mercenary, then train to acquire new weapons, participate in 1v1 and 2v2 combat and bring glory to your faction. ED offers plenty of variety for a Flash game—players can customize their characters well enough; skills are plentiful as are items and achievements. Matchmaking is quick and, even though ED doesn't have a tutorial, it’s easy to grasp. 2v2 battles are the game’s salt—highly addictive, plus they do require some knowledge of both your opponents’ and your own skills. That being said, ED is definitely a game to be played in short bursts, otherwise it gets repetitive because there are only two game modes. The in-game currency gives advantages to those who pay. However, as there’s always something to do in the ample game world, and as the matchmaking is that simple… logging in and fighting for a bit is just too easy to find serious fault with this game.See Videos

Eve Online is an ambitious sci-fi MMORPG. With a single, engrossing universe having about 40-50 thousand players online simultaneously, Eve Online is very much a landmark game. The action taking place in a galaxy called New Eden. Players pick from five races and team up in Corporations -- ‘corps’ for short -- to gain dominance with their starships in breathtaking, complex battles. The graphics are stellar and, along with game content, have been updated regularly since Eve’s 2003 release. Eve is a second life to many, and with reason. Players get by with piracy, manufacturing, exploration, combat, and more -- to each his own. Eve Online has all the trappings of a typical MMORPG, but it's also much more -- it’s actually one of the richest online gaming experiences nowadays. Before you start, however, know this: the learning curve is an steep; the game is PvP-centric; and, finally, it’s nearly impossible to enjoy Eve without social encounters.See Videos

Exoplanet war is an online strategy game. The game is set in a sci-fi setting reminiscent of the Warhammer universe -- three races are struggling for victory on a planet Xenos that is the only source of a rare resource, called... Xenos. The player is given a fresh, non-developed colony on the planet, and has to build buildings, gather resources, form alliances with other players or engage them in combat when their army is big enough. Players can also raid rebel forces (monsters) on the planet and complete quests to gain resources faster. There are lots of unit types (infantry, vehicles, air, defensive, offensive, etc.) and the game is a challenge for anyone who enjoys military strategy. The game does have a "pay up" attitude, as its paid features are presented to the player somewhat aggressively.

Firefall is an MMO/Shooter set in a sci-fi universe where Earth is under attack by extra-dimensional aliens. From the very outset the game captivates with great graphics, intensive battles and a story (played in an open world) that echoes the epic scale of Pacific Rim. There’s a massive single-player campaign played out with hundreds of other players. Each of the five classes has a significant role in combat, which reminds one of Tribes. There are also jetpacks that make everything much more intense and fun. MMO elements like crafting and mass-invasion events make Firefall stand out even more. Not to say that it’s all rainbows and unicorns all the way, though: there’s not enough content, and progressing through levels is patchy. PvP can get laggy, but classes aren’t that balanced as of now. Overall, though, Firefall is definitely one of the most intriguing F2P shooting titles out there.See Videos

Infinite Realms is a sci-fi themed MMO strategy game, played through Facebook. Players have to build production structures, upgrade their outposts, train troops and recruit heroes to conquer new areas, build alliances and fight both player and computer enemies (mobs). Although the game doesn’t offer much originality, it is the sci-fi setting that has its appeal. If you’re one for stories, the game offers "mission text" for each mission you’re given, and the missions are daily. Infinite Realms is by no means a game that could earn the title for ‘most innovative Facebook game’, but it’s playable and has a somewhat small but friendly community.

Use precision aim, jetpacks and skiing (continuous jumping to pick up momentum) to subvert attackers and dominate in your flag capturing duties.
