A few hours ago Arma 3 Marksmen DLC was made available. The DLC comes with seven new weapons and some other interesting things, but you can make up your mind about how it is, by seeing the launch trailer posted below.
Marksmen DLC is available for 12.99 EUR/10.99 GBP/15.99 USD via Steam or the Bohemia Interactive Store, or you can buy the Arma 3 DLC Bundle that includes: Arma 3 Karts, Arma 3 Helicopters and this DLC. The bundle is priced at 19.99 EUR/16.99 GBP/24.99 USD, which is more than 25% cheaper than the case in which you would buy every piece in it.
Hone your shooting skills and engage in ranged combat with the seven new weapons in the Arma 3 Marksmen DLC.
