What Is TacSim?
Tactical Simulation (TacSim) is 007 First Light's mission replay and challenge mode, developed by Dr. Selina Tan at MI6's Tactical Simulation department. It allows replaying campaign encounters with modifiers, new objectives, and remixed combat scenarios. Access requires an active internet connection.
How to Unlock TacSim
TacSim unlocks automatically during Chapter 6 (A Night Out) when you first speak with Dr. Selina Tan in Q-Lab. After the story credits, you can also access it directly from the title screen.
Two Modes: Escalations and Operations
Escalations (unlock after Chapter 6):
- Remixed versions of campaign encounters
- Conditions and objectives change each run
- Three tiers of increasing difficulty
- Best for farming combat achievements
- The "Advanced Tactical Training" Escalation is recommended for Tier 3
Operations (unlock after story credits):
- Full mission replays with campaign-quality objectives
- More comprehensive than Escalations
- Best for earning the "A change of pace" achievement
- Each takes approximately 3 minutes to complete
Clearance Level System
Your clearance level increases by completing Escalations, Operations, and Challenges. Reaching Clearance Level 3 unlocks the "Keep moving forward" achievement. The level increases naturally while completing the other TacSim achievements — no extra grinding required.
Future Content — Valhalla Protocol
IO Interactive has teased "The Valhalla Protocol" — an in-game advertisement that appears after the credits. This appears to be a future TacSim mission featuring the Aston Martin Valhalla. CDO Véronique Lallier confirmed that new TacSim content is already planned and a roadmap will be released.
