TacSim Mode in 007 First Light Explained
TacSim is the replay layer sitting alongside the main campaign in 007 First Light. Short for Tactical Simulations, it's a separate mode run inside the fiction by Dr. Selina Tan, head of Tactical Simulation at MI6, where Bond returns to campaign locations under new rules, modifiers, and objectives. It's where every cosmetic outfit, weapon skin, and gadget upgrade in the game lives, and it's the only place you'll use them.
🎯
Quick answer: TacSim is an endgame mode accessed from the Main Menu. Complete simulation missions to earn Intel and Clearance XP, then spend Intel at the Intel Shop on outfits, weapons, gadgets, and skins that only function inside TacSim.

What TacSim actually is
The mode is presented in-world as an MI6 training facility inside Q Branch. From a central hub, you pick a mission and an outfit, then walk into a simulation chamber where the environment reconstructs a campaign location. The Intel Shop sits just before the simulation room itself, down the stairs from the main hub.
Mechanically, it's IO Interactive's take on the escalation format from the Hitman series, adapted to Bond's faster, more linear style. Campaign maps are reused, but objectives, restrictions, and enemy behavior change.
Escalations and Operations
TacSim splits its missions into two categories with different structures.
| 007 First Light TacSim Escalations — Image Credit: IO Interactive Type | Structure | When it unlocks | Focus |
|---|---|---|---|
| Escalations | Three tiers per trial, each tier adds restrictions or new conditions | Iceland and Malta unlock right after their story missions; the rest unlock after finishing the campaign | Short skill trials covering combat, stealth, or improvisation |
| Operations | Single tier, sandbox-style objectives | Endgame content, opens after the main story | Longer sub-missions with multiple approaches |
Each mission also carries a set of side challenges, typically seven to ten per simulation, that reward extra Intel for specific actions like using a particular gadget at a set point or finishing without being spotted.
Game Changer modifiers
Escalations don't just raise difficulty by buffing enemies. They change the rules. A tier might disable gadgets entirely, restrict you to ranged weapons, require headshots to kill, or fail the mission instantly if stealth breaks. Some scenarios also randomize the placement of objectives like hidden notes or data discs, so memorizing a route from a previous run isn't enough.
TacSim also broadens the sandbox in the other direction. Gadgets that are gated in the campaign are generally available here, and IO Interactive has said it will add new interaction points for gadgets across these levels over time.
Intel, Clearance Level, and the Intel Shop

Two currencies drive progression. Completing simulations and their challenges pays out Intel, while finishing missions awards Clearance XP that increases your Clearance Level. The Intel Shop checks both: you spend Intel to buy an item, but you need the matching Clearance Level to access it.
Mission tiers and the early Iceland and Malta simulations each award around 100 Intel. The Intel Shop stocks:
| Category | Notes |
|---|---|
| Outfits | Includes pre-order, special edition, and promotional outfits; usable only in TacSim, not the campaign |
| Weapons and weapon skins | Alternate firearms and visual variants |
| Gadgets and gadget upgrades | Includes upgrades such as added damage for the Q-Watch laser strap |
| Gadget skins | Cosmetic variants for Q's equipment |
Bond's wardrobe in the main story is narrative-driven, so anything you unlock here stays inside TacSim. There is no New Game+ that carries TacSim purchases back into the campaign.
Agent Score and leaderboards

Every run is graded into an Agent Score that factors in speed, takedown style, cameras disabled, and similar performance metrics. Both Escalations and Operations feed global and friends leaderboards, so a clean, fast solution beats a thorough but slow one.
How to access TacSim
Step 1: Finish the early Iceland and Malta training missions in the campaign. The TacSim versions of those two levels unlock immediately and act as an extended tutorial for the mode.
Step 2: Open TacSim from the Main Menu. Walk down the stairs to find the Intel Shop, then continue into the simulation room to pick a mission and outfit.
Step 3: Complete the campaign. After the credits, the remaining Escalations and all Operations unlock, opening the full mode as endgame content.

Post-launch additions
TacSim is the part of 007 First Light that IO Interactive plans to keep updating. New simulation missions, gadgets, and interaction points are slated to arrive after launch, expanding the pool of levels, modifiers, and rewards beyond what's available at release.
⚠️
Note: TacSim requires you to engage with it on its own terms. Outfits, weapon skins, and gadget upgrades earned here cannot be brought into the main campaign, and there's no New Game+ that changes that.
If you treat the campaign as the cinematic side of 007 First Light, TacSim is the systems-driven counterpart, closer in spirit to Hitman's escalations than to a traditional mission replay. It's where the leaderboards, the cosmetics economy, and the long tail of post-launch content all live.
