Steam started another Free Weekend yesterday. You can play Nation Red for free now through to Sunday 15th January, 1 pm Pacific Time.
If you enjoy playing the game, you can also buy Nation Red this weekend for 75% off the regular price. The sale ends Monday 16th January at 10am Pacific Time.
The game seems pretty fun and for the price you can’t really go wrong. It’s like a mix between Killing Floor and a twin stick shooter. I would recommend playing it with others for the best experience.
