Disclaimer:
Before purchasing Sierra Ops - Please note that the game was originally a free-to-play episodic game. However, due to visibility issues, Valve suggested we switch to paid app with both episodes 1 and 2 in it. This means Sierra Ops is now technically an Early Access title.
The price of the game is currently $14.99 USD which includes episodes 1 and 2. Once the full expansion patch is released, the price will be adjusted to $24.99 USD (cheaper than initially planned with episodes 2-4 as $9.99 USD x 3 DLCs). We sincerely apologise for any confusion this may have caused.
