Ash: AR, shotgun, pistol, SR Garrus: AR, pistol, SR Wrex: AR, shotgun, pistol Tali: Shotgun, pistol Kaidan and Liara: Pistol In any case, they can use other guns ... they just probably won't hit the broadside of a barn with them. The first time I hit the Thorian's lair on Feros my soldier had Kaidan and Liara along; I decided to try equipping them with shotguns and hammerhead rounds. I found out that this is inadvisable because they ended up knocking my butt on the ground due to hitting me more often than the creepers. Generally I say the hell with the advice regarding a "balanced" squad; I need somebody to crack locks and salvage gear and after that I grab my best straight up fighter(s). However, this last playthrough was the first time I took Liara to the final party, and I was pretty impressed how quickly she, Wrex, and my engineer took care of the husk-ified Saren. Biotics and tech were vastly scaled down in ME2 - they do more damage to individual targets, but you can't just have Liara, Kaidan, or an adept Shep go completely Carrie: The Rage on an entire room of bad guys. As a further note, in my sentinel playthrough I took Ash and Wrex to the final mission. It's rather amusing to have Ash be the one arguing for you to save the Council.
