Doc's Elite set is now available. Includes the No Man's Land weapon skin for the MP5, P90, SG-CQB, LFP586, and P9. Also comes with the Elite Doc Chibi charm, Trench Medic uniform, They Shall Not Pass victory animation, and the Vintage Medical gadget skin for his Stim Pistol.
We've always firmly believed that gameplay content shouldn't be locked behind a paywall. All customization items, including weapon skins, headgear, uniforms, and weapon charms, are purely cosmetic.
