Hijack the International Space Station and retrofit laser cannons. That's Captain Forever. With one hand on the keyboard you duck and weave through an endless universe of hostile star-ships, your own weapons tearing at their hulls. Each vessel is a flotilla of girders, boosters, and lasers welded in a unique configuration. Blast open an enemy's command module and these components drift freely into space. With a quick hand on the mouse you scoop these up and weld them to your own ship, building yourself stronger, faster, more dangerous. Be careful though - your design dictates your flight characteristics. Put all your weight or boosters on one side and you'll fly in circles. Aim a laser in the wrong direction and you could shoot off your own wing! In Captain Forever you can build a dreadnought brimming with lasers or a sleek starfighter. The choice - and the ship - are yours, Captain. Captain Forever is a free web game with supporter-only sequels.
These screens were captured for the launch of Captain Successor, the first Captain Forever sequel available only to supporters. They show many (but not all) of the new modules and enemy configuration algorithms.
To create these screens I made the game save a screenshot every five seconds, then played it many times through. I picked these out of over a thousand shots :)
