Alpha 4 is now live with the new trading system along with several new ships and bug fixes. For more details on the patch check the notes below and for insight into what's next check out the latest post on the Space Impossible Blog

Release Notes

New Trading system

• Added currency to the game. This is seen in your inventory, below your current vessel's name
• Added the trading system. This allows you to buy and sell with AI controlled ships and space stations. To access a vessel's store, there is a OPEN STORE button below its name. To sell, pick up items with the mouse, and click on the SELL area on the center bottom left. Right click will sell one item at a time, left click to sell a whole stack.
• Different factions will sell some general basics as well as some specific items. Of most interest, each faction will now sell a limited supply of ship kits for their faction ships.
• Sell prices for items in inventory should appear on the tooltip while in your inventory and browsing a shop.
• Added trader hub component to ships and stations.
• Added new trader ships to each faction. You should see these flying about now instead of Tradesman everywhere.

Other

• Added basic Station AI. Stations that spawn in a region now generally belong to the same faction as that which controls the region. If hostile, they will shoot at you if/when possible.
• Modified region templates to allow larger diversity of stations spawning.
• Fixed a bug from Alpha 3 where warp chambers were being ignored on tile death.
• Some improvements to AI movement. They will now attempt to engage in combat at different angles better, and will react to what weapons they have.
• Kal'giri ships start off with Comblastors
• Fixed a stackoverflow bug where resuming objects under construction weren't capable of finishing.
• Changed some core logic for the repair graphics to better detect edges of the ship/station.
• Repairing vessels like the K'Eziru should no longer be able to repair portions unconnected to the current tiles.
