Taken from Mercenary main official site, futures section...
1. Cooperative multiplayer objectives that pay all linked players. Join forces with other players to complete more challenging activities that can offer much better pay. More advanced players can link with new players to give them access to higher paying contracts that they would not otherwise have access to early in the game. Being part of the same team lets you combine reputations and contract pay for improved results.
2. New gun turret binding mode in multiplayer allows players to link their ships together. One player controls a 360-degree gun turret attached to the player's ship they've linked to.
3. New fleet command system. Send single player commands to AI ships and multiplayer commands to other players. You can order your fleet ships to form up, attack hostiles, defend you specifically, mine asteroids, or order them to reload and refuel which parks them in a local station until ordered to do something else. In multiplayer, the new command system broadcasts the order in a message, so clans can use the same command system to issue orders to their human wingmen.
4. Ship-to-ship trading and cargo system. Ship and trade weapons, upgrades, fuel, credits, and equipment in addition to commodities. You can even load items from your cargo bay onto your ship, letting you carry more weapons, upgrades, and equipment beyond what you can install on your ship. Challenge other players to multiplayer ship-vs-ship races with the trade console and place the race course where you want in space.
5. The new build system lets you construct space stations, dynamically expanding the game's universe with new trade routes, docking points, and economies. The online multiplayer universe system supports this station placement, letting you or any other player construct stations at new locations in the game's universe while you are playing online. Player built stations are stored with the server so other players can have access to the new stations and trade routes you create.
6. New clan territory control system. Clans can take partial control of solar systems through cooperative contracts and clan-vs-clan battles in multiplayer. The server tracks events involving completed contracts and clan wars, then awards percentage points to victorious groups, giving them a partial ownership interest in the system. When clan control is above 80% in a system, they are paid a percentage of earnings from that system.
7. Unified gameplay architecture and profiles let you keep the ship, upgrades, equipment, money, weapons, crew, and commodities you acquire in the game for use in both single player and multiplayer.
8. New Multiplayer system with much higher performance for improved precision and gameplay. Integrated voice chat lets you talk with other players using your PC's mic.
9. Clan ID linking system lets you establish your indicated threat levels with other players in multiplayer. Players sharing a common ID in their callsigns are linked together as friendly contacts while different ID's are indicated as hostile. You can also link together in-game with another clan to form a larger group for better odds of success.
Something like that
