[PC] Origin - Medal of Honor - £1.59 (~$2.88 AUD) - Gamersgate UK

Pretty good deal for a fun game. Campaign is relatively short at 4-5 hours but as far as I am aware MP is still active although the playerbase is very low.
I reckon the campaign is well worth the admission price.
Only available for another 3 hours or so.

From the website:

Buy Medal of Honor as a Origin Key.

Operating directly under the National Command Authority, a relatively unknown entity of handpicked warriors are called on when the mission must not fail. They are the Tier 1 Operators.

Over 2 million Soldiers, Sailors, Airmen and Marines wear the uniform. Of those, approximately 50 thousand fall under the direct control of the Special Operations Command. The Tier 1 Operator functions on a plane of existence above and beyond even the most highly trained Special Operations Forces. Their exact numbers, while classified, hover in the low hundreds.

They are living, breathing, precision instruments of war. They are experts in the application of violence. The new Medal of Honor is inspired by and has been developed with Tier 1 Operators from this elite community. Players will step into the boots of these warriors and apply their unique skill sets to a new enemy in the most unforgiving and hostile battlefield conditions of present day Afghanistan.

There is a new enemy. There is a new war. There is a new warrior. He is Tier 1.
