Late last week we updated the Rising Storm beta application to add in the Search and Destroy gametype and maps. Like with the Maggot Hill playtests we will be testing every day this week at 3 PM (EST). You'll be able to find the events (and the local time for you) over at the events page here: http://steamcommunity.com/games/RO2/events/
Search and Destroy for those who may not know the gametype, is a single life gametype in which once team has to destroy one of multiple objectives by planting an explosive. The defending team needs to stop the attackers from planting, or diffuse the explosive before it goes off.
We look forward to seeing you in the first test later today (remember it is in the Rising Storm Beta application in your Steam Library)!
