GoldenEye 007 on Nintendo 64 - Agent Mission 6: St. Petersburg - part iii: Streets

1. Pursue Ourumov and Natalya
2. Minimise civilian casualties

It's on Agent difficulty that you unlock the "Streets" cheat code. Not too complicated.

a. Pursue Ourumov and Natalya

First take the tank - it's faster and more powerful than James on foot :D. Besides the first crossroads where you need to go right (left is the dead end where you find Valentin), there are 2 forks in the level. Before the first one, 3 cars block your path. To avoid taking too much damage, I'd still recommend blowing one up, though you can also try hugging the left wall. If you destroy a car, kill the guard in the corner just before it first - he has a rocket launcher. At the first fork, I recommend going right (then right again to rejoin the common path). This is the minefield route, but if you go through the "left-right" quickly (almost straight ahead), you avoid the rocket launchers on the left path. Before tackling the mines, kill the 3 guards ahead (and at least 2 of the previous 3 while you're at it). For the minefield, a well-placed shell will clear a path, but you can also remove one mine to be safe. Take the left turn wide so you can fire straight down the "left-right" as I mentioned earlier. Then avoid the cars on the left and clear a path through the minefield to reach the second fork. Again, I recommend the right path - a bit longer but safer. Quickly kill the 3 guards at the corner and clear the last minefield. Turn right at the crossroads and weave between the cars to reach the end of this level. I recommend watching the 00 Agent video, it's clearer than this text :).

b. Minimise civilian casualties

For my walkthrough, I always count how many people you need to kill before the mission fails. In Facility and Silo, no problem, but here... very tricky. In fact, I started the game on 00 Agent, and failing this objective turned out to be more complicated than finishing the level :D. I'd say you need to kill about a dozen to fail, which is more than the level seems to contain by default, so I had to keep circling around until civilians respawned in order to fail... After around 7 civilians, the game warns you that the civilian casualty level is high :).
