Captain Forever

Captain Forever is a single player space shooter game that is free to play at captainforever.com. You start out as a small red ship and are given two green boosters, two green guns and four green blocks. You can make your original ship out of these materials however you like. After you have your initial ship, you can fly off and fight other ships. The first ships you'll meet will be made out of green materials. What you don't destroy in your fight with the ship, you can use to build your own ship. After you defeat a few green ships, yellow or orange ships will start appearing. Yellow stuff is stronger then green stuff and yellow guns are like semi automatic green guns. After you've destroyed a few of those, red ships show up. Red supplies are pretty strong and should be valued. Red guns are the fully automatic versions of yellow guns. The next type of ship you will see will be a purple ship. The purple items are once again stronger but the guns fire a new kind of bullet. The other guns shoot a red bullet but this ship fires a yellow bullet. After these ships, blue ones will come. The blue guns are faster in terms of shooting then the purple ones. The next highest ship is white. The white guns shoot larger white bullets and have stronger materials. After these come rainbow ships. The rainbow parts turn gray when not attached to another ship and are to white parts as blue parts are to purple ones. These are all the main ships but there are others that are in between these. A list can be found at the wiki. There is another type of gun that comes in all colors and is called a prismatic laser. It fires three shots instead of one but is very rare in the free version. There is also a paid version that costs 9 dollars and can be obtained at the site. I may talk more about that version in another post. But even in the free version you can create amazing ships like this one: 

a very advanced ship

have fun gaming,
