The Throwdown is a secret achievement/trophy in Deus Ex: Human Revolution. To complete it, you must engage Bill Taggart first in the convention speaking hall (and not in the backstage dressing room), then persuade him to tell the truth.
Use the Confront response against Taggart as your first response to his dirty politics, and then follow-through with the rest of the conversation.
Remember the following when selecting your follow-up answers:
- Your goal is having Taggart admit his part (or his aid's part) in the Sarif HQ attack.
- Taggart is a prima-donna, so personal attacks will undermine his confidence in replying, setting you up for your next reply.
- If Taggart has no information to exploit, his arguments are generally based on his personal ideals.
- Lastly, you can threaten to give the recording to the reporter or press to test its genuine status, and that will pressure Taggart into telling the truth in public.
An alternative solution is to use "Discredit" as follows: 1. Discredit, 2. Redirect, unless Taggart says "My heart goes out to you" (in which case use Confront), 3. Discredit, unless Taggart mentions that he is a psychologist (in which case use Confront), 4. Discredit. This path has a 100% success rate.
A third alternative would be to use CASIE pheromones when given the chance, then use Appease for the alpha type personality. Other options will fail the conversation.
Another approach is to pay less attention to the CASIE reading and make your choices based on his psychological profile.
