There's now an option under the controls tab of the menu for changing the perspective between first and third person.

I'm interested in receiving some feedback from players on what they feel should be improved or changed. This is my first game so I'm guessing there are many suggestions that could be made so feel free to share your thoughts in the discussions section.

A memory leak previously caused by the bullet hole decals and impact particles not being released properly has been removed. You should find that the reported memory usage is no longer rising over time causing the game to crash if you remain in an environment for too long.

Trading cards, emoticons, badges and backgrounds have been added and will be enabled once Valve considers the game to have reached the necessary thresholds.

This update smooths the terrain to ensure it's easier to traverse while the physics issues with the hovercraft have been dealt with and the enemy behavior polished further.

The DLC provides access to past trailers, music, renders, sketches, voice recordings and other behind the scenes content over the four years of development as well as a playable pre-alpha demo.

This update brings revisions to the core game-play experience including improved level design, pacing and enemy behavior. A number of issues affecting the game have also been fixed.
