Difficult sections and useful strategies
Strengths
- Frequent objective markers make the intended route readable
- Character switching or team roles can divide pressure
- Most combat checkpoints provide cover or a defensible angle
Weaknesses
- Mission-critical vehicles and allies can fail the attempt
- Police or enemy reinforcements punish slow extraction
- Long pursuits can be lost by overcommitting to shortcuts
Best uses
- Clear enemies from range before moving a required vehicle
- Use special abilities during the hardest driving or combat segment
- Restart from the latest checkpoint after a failed gold-medal attempt rather than improvising a damaged route
