- "Snipers in position."
- — Archer, beginning of Loose Ends.
He appears in the mission "Loose Ends" as part of Sniper Team One, wearing a ghillie suit and providing overwatch for the strike team (Roach and Ghost). He and his partner Toad provide very critical help during the take down and defense of Vladimir Makarov's safe house, providing information on oncoming enemies, sniper support, and taking out two armored trucks that were escaping from Makarov's safe house with Javelin missiles.
As revealed by radio chatter shortly after the mortar strike kills Ozone and Scarecrow and injured Roach, Shadow Company was aware of Archer (and Toad's) presence, and called in counter snipers with thermal vision to dispose of them.
They were both killed by these counter snipers mere moments before Shepard's betrayal, leaving them unable to warn or save the duo.
- Archer and Toad can be killed by the player at the beginning of the level. If the player plants and shoots a claymore causing the explosion to kill them then they will not be penalized for friendly fire. The level will still proceed normally even including the scripted dialogue from Archer.
