The interrogation reveals the existence of the Nemesis T-Type, a powerful bio-organic weapon (BOW) deployed by Umbrella to eliminate S.T.A.R.S. members. Your new objective is to track and eliminate this threat before it causes further chaos. Follow the objective marker through the ravaged streets, which are now even more dangerous with the presence of the Nemesis.
You'll encounter the Nemesis multiple times during this pursuit. It is heavily armored and carries a rocket launcher. At this stage, you cannot defeat it. Your goal is to survive its encounters and drive it away. Focus fire on its exposed head or use explosives to stun it, allowing you to escape. The pursuit will lead you to a specific location where a more direct confrontation is inevitable. This sets up a major boss fight later in the campaign.
