The Price of Revenge is a engaging addition to the Mass Effect 2 story which includes the acquisition of a new squad member, Zaeed. The content is well incorporated into the game and favours the player completing it prior to undertaking the Suicide Mission.
It's worth noting however, that although the content is advertised as two new missions, the first mission is more of a conversation in the entrance to Omega, no combat or exploration is needed, and the mission is complete within a couple of minutes. So thankfully, the loyalty mission makes up for this deceiving advertisement, with an in-depth mission, full of new conversation options, upgrades, and quirky cut scenes.
Zaeed is present on the Normandy SR2 for the duration of the play through, he is a usable squad member and can be used in any story mission from the point of his acquisition. The player can also visit him in his quarters on the ship, a funny addition is the garbage disposal airlock, where the player can interact with and shoot out the garbage into space, watching from the window.
