How can I counter enemies with Riot Shields in Mass Effect 3
The playstyle is mostly rushing with the shotgun, and also using melee attacks. Now the trouble is with the guardians (the cerberus guys with the shields). Rushing just doesn't work, and aiming on their feet with a shotgun or trying to run around them doesn't work either. The trouble is their shield. I can use the push power on them and then try to get in a melee attack but they recover too fast to use the power melee attack.
Is there a way to take their shield away?
Edit: to be clear this is close combat only, a sentinel doesn't have pull, or i don't use the sniper rifle.
