Am 23. September 2013 wird Valve Software das First-Blood-Update für Dota 2 veröffentlichen. Die Aktualisierung umfasst einen "lokalen Modus", bei dem man lokale Spiel-Lobbys erstellen und somit eine Partie im lokalen Netzwerk (LAN) oder innerhalb eines Internet Cafés einrichten kann. Hinzu kommt die Captain's-Draft-Option: "Versammeln Sie ein Team, wählen Sie einen Kapitän und bezwingen Sie Ihre Gegner in einem Wettstreit, um eine Squad aus einem zufälligen Pool von 24 Helden zu bilden. Jedes Team wird abwechselnd (während Pick und Counter-Pick) zwei Helden der Auswahl entfernen dürfen, um die Zusammensetzung der Aufstellungen vor der Schlacht zu bestimmen." Zudem wird der Rucksack (Inventar) in das Waffenarsenal umgewandelt, in dem man mit speziellen Filtern (Itemtyp, Qualität, Seltenheitswert etc.) suchen kann.

Im Shop wird es neue Schatzkisten mit Rüstungen, Waffen, Masken, Haarschnitten und Co. geben sowie das "Portal Paket": "Den dunklen Humor von Portals GLaDOS gibt es nun endlich auch als Dota 2 Ansagerpaket! Die sarkastische K.I. wird Ihnen nur allzu gerne Bescheid geben, sobald Ihre Baracken oder Türme zerstört werden. Im Umfang dieses Pakets erhalten Sie auch neue Aperture Science Wards sowie das Portal HUD Skin, die beide nur durch den Kauf dieses Portal Pakets erhältlich sind."
