 The man at arms is equipped with a halberd,a mace with a small shield and a smaller version of the Archer crossbow.His special attack is "farting" that makes enemies slow and damage them at the same time.The archer and man at arms are both like a skirmisher,they have less health than other classes but run and attack faster in quick blows.Soon after the release of "Half-Life 2", the Valve released a software development kit (SDK) for the game's Source engine.
