Mass Effect 2 beginner guide: Omega, Mordin and squad preparation
Build an early team, open the research lab and develop powers before the late-game story accelerates.
Original Mass Effect 2 (2010), with original PC publisher images; not the Legendary Edition remaster. Core recruitment and finale advice applies to the original campaign. Zaeed and Kasumi require their original downloadable content and are optional alternatives where named.
Use cover and command your squad
The opening missions teach the move-and-cover loop. Let shields recover behind solid cover, then attack during a safer opening. Use the power interface to select targets for your companions instead of relying entirely on their automatic decisions. A squad power used at the right moment can remove protection before Shepard commits ammunition.
Make the Professor an early Omega stop
After obtaining the Normandy, travel to Omega and pursue Dossier: The Professor to recruit Mordin. His arrival activates the research lab, making upgrade data and minerals useful. This is an editorial opening recommendation rather than a mandatory first dossier: it gives you access to improvements while you complete the remaining recruitment missions.
Build around a few useful powers
Power ranks become more expensive as you advance, and rank four offers an evolution choice. Develop a dependable combination instead of distributing every point evenly. A damage power, an answer to the enemy’s protection and a class-specific ability create a clearer plan than several barely developed powers competing for the same cooldown.
Leave room for conversations and preparation
Visit the squad between missions, read the journal and follow up on personal requests. Loyalty and Normandy research influence the finale. Before launching the later Reaper IFF assignment, complete the preparation you already have available. Keep a separate manual save before major story commitments so a rushed decision is easier to revisit.
Recruiting Mordin early turns the resources you collect into upgrades while there is still a long campaign ahead.
