Bionic Commando: Rearmed - Valve
Capcom's critically acclaimed, beautiful re-imagination of the classic NES game you should not miss...is available at 50% off during this week's Midweek Madness sale. Offer Ends Thursday at 4pm Pacific Time.

Classic side-scrolling gameplay is reporting back for duty with Bionic Commando Rearmed, a remake of the classic NES game. 20+ years after the 8-bit classic was released, Bionic Commando Rearmed recreates the world of the original with a complete "2.5D" visual revamp. Bionic Commando Rearmed preserves the original's mix of swinging and shooting in an intense 2D side-scroller, all to the tune of a brand-new soundtrack based on the classic 8-bit music from the NES masterpiece.

But Rearmed is far more than just a remake - it features all-new modes such as the 2-player co-op play, smarter enemy AI, new bionic arm abilities, new weapons, bigger bosses and online rankings. Faithfully sticking to the story of the NES game, Bionic Commando Rearmed tells the story of Nathan "R.A.D." Spencer's first mission, sent in to retrieve captured agent Super Joe from the hands of the Imperials. Fans of the original story can expect to see all the characters from the NES version, as well as the memorable moments that made the title so popular with fans.

Star Ruler - Valve
Updates to Star Ruler have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

Fixed:
  • A long lag before joining a multiplayer game in progress that appears as a freeze (but eventually does connect).
  • Modded EmpireNames.txt and EmpireColors.txt are now used in the lobby.
  • Tips files were showing up as languages.
  • Freeze when holding alt for range rings while hovering on an enemy unit.
  • Antimatter generators would not explode when disabled due to lack of control.
  • Queue management commands did not work for dry docks in multiplayer.
  • Light/Heavy/Stealth hulls were incorrectly scaling with level, making them much too powerful at later tech levels.
  • Ships can now be retrofitted / scuttled at dry docks.
  • The victory message was not showing up when eliminating all enemy teams in a team game.
  • Docking stations into planets or carriers could crash.
  • Starting a multiplayer game with teams could crash due to timing issues.
  • When hovering over a sub system with a modifier/link attached to it, the correct stats will now be shown on the left.
  • Overriding controls that had a default key assigned to them would create duplicate bindings and not be displayed correctly in the options menu.
  • Hotkey groups are now saved and loaded.
  • The Rack Mount was misbehaving at small scales. It now behaves much more sensibly at all scales.
  • Fixed jittery movement of ships in multiplayer (except in very high-lag situations).
  • Manual transfer orders did not work for MP clients and did not save.
  • The order list on completely idle ships would not properly display for clients.
  • Boarding defenses were not scaling up, making them wholly ineffective.
Changed:
  • Nano armor hitpoints and damage reduction now only increase with armor research, while regeneration rate increases with nanotech research only.
  • Multiplayer server names now default to "'s Game".
  • Clicking the planet lost message now zooms to the system the planet was lost in.
  • Version compatibility is now checked before joining the lobby, instead of after starting the game.
  • When a treaty ends prematurely because of one party lacking the required materials / research, a message is now displayed.
  • Use tool only appears in the right click menu if the ship could actually use that tool on the clicked object.
  • Stations built from orbital dry docks now correctly orbit the original planet.

  • Arrow key movement speed now changes more drastically with zoom level, instead of being exceedingly slow when zoomed out.
  • Zoom in now locks on to the system plane, so missing a target will no longer zoom "through" the system.
  • The Remnants now use designs with more advanced technology in them. Analysing or boarding their designs will let you build high-tech toys much earlier.
  • The system rings are now larger so as to fully contain the bounds of the system.
  • Space damage is now percentage based.
  • System ring owner color is now based on military strength rather than pure ship count.
  • Systems are only marked as under attack if either you or the enemy have military presence.
  • Systems that are contested now glow rather than their ring changing color.
  • Distant icons for ships that are taking damage now glow.
Balance:
  • All armor levels are now equalized, making more advanced armor more viable.
  • Ablative armor now scales the same way as other armor, giving it significantly more hitpoints at higher tech levels.
  • Torpedoes now use less ammo.
  • Planets now have a damage resistance related to cities, capitols, and bunkers. This scales with level, increasing their longevity late-game.
Added:
  • Savegames may now be deleted in-game.

  • Dedicated server binary to run a server without playing or rendering the graphics.

  • Moving your mouse to the edge of the screen now moves the camera. (Can be turned off from the options menu).
  • Options menu settings for ambient brightness and multiplayer server autosave.
  • 3D movement orders: Double right clicking and holding the right mouse button now lets you adjust the vertical component. (Also works by holding control, single right clicking and holding)
  • Added support for scripted planet queues. Use '<script call="Module::Function" />' in a queue to use a function of the type 'bool Name(Planet@).' Return true to prevent the rest of the queue from running.
  • A grid is now displayed on every system's XZ plane. (Can be turned off from the options menu).
  • Added 'OrderList::leaveFleet()' to remove a ship from its fleet.
  • Added a new weapon: Artillery. Huge range, massive damage, but very slow fire rate. May only be equipped to stations.
  • Added log & log10 functions for formulas.
  • Added new planet conditions: Plains (Cheaper buildings), Volcanic (Weaker buildings), and Geothermal vents (Faster electronics/advanced parts production).
  • Empire messages now have a category. Categories can be toggled on or off when expanding the ticker display.
