007 First Light TacSim Mode Guide: How to Unlock and Master It

007 First Light skips New Game+ entirely, and TacSim is the answer to that gap. Confirmed by IO Interactive ahead of launch, this post-game mode lets you replay missions with challenge modifiers active, unlocking cosmetics and gadgets you won't find anywhere else in the campaign. If you're planning to squeeze every hour out of this adventure game, TacSim is where the replay value lives.

What is TacSim mode in 007 First Light?

TacSim is a dedicated mode set inside Q Lab, framed narratively as a new training program for MI6 agents. According to Art Director Rasmus Poulsen, it exists as a physical location within the game world, guided by a character who is enthusiastic about pushing agents through experimental training methods. That framing gives it a bit more texture than a plain mission select screen.

The mode functions similarly to the Freelancer mode from the Hitman series, but the focus here is on replaying specific levels with modifiers rather than stringing together a roguelite campaign. Senior Communication Manager Yann Roskell described it as a way to "create new ways of playing and then adding even more creativity to how players can handle the challenges."

How do you unlock TacSim missions?

The unlock structure is straightforward. The first two missions in the game have their TacSim counterparts available as soon as you finish them for the first time. You do not need to complete the full campaign to access those early replays.

The remaining missions unlock their TacSim versions only after you finish the main campaign. So if you want full access to every modifier run, you need to see the story through to the end first.

What modifiers does TacSim include?

IO Interactive has confirmed at least two modifier examples so far. One removes all gadgets entirely, forcing you to rely on melee and environmental reads. The other restricts ranged combat to headshots only, meaning body shots deal no damage at all.

Those two examples alone suggest the mode is designed to pressure players into approaches they wouldn't naturally choose. The gadget-free run in particular will be a serious test given how much the watch hacking tool and disorientation darts factor into stealth routes during the main campaign.

What rewards can you earn in TacSim?

Completing TacSim challenges unlocks new gadgets, suits, and additional cosmetics. IO Interactive has not published a full reward list ahead of launch, but the confirmed categories are gadgets and suits. For a closer look at every outfit in the game and how they're obtained outside of TacSim, the 007 First Light suits and outfits unlock guide covers the full picture.

The key point is that some rewards are exclusive to TacSim. If you want everything the game offers, the mode isn't optional content you can ignore after the credits.

How does TacSim compare to a traditional New Game+?

A standard New Game+ would carry your unlocks into a fresh playthrough, letting you experience the story again with more tools available. TacSim does something different. Rather than replaying the narrative, it strips context away entirely and focuses on mechanical challenge.

The upside is that it targets the parts of 007 First Light worth replaying, which are the open-ended mission structures, not the linear cinematic sections. The Kensington level alone has multiple confirmed infiltration routes that most players will miss on a first run, and TacSim modifiers give you a reason to go back and find them.

The downside is that players who wanted to experience Bond's origin story again with different dialogue choices or a different approach to key moments won't get that here. TacSim is a systems challenge, not a narrative replay.

Tips for getting the most out of TacSim

Based on what IO Interactive has confirmed about the mode and the mission design philosophy behind 007 First Light, here are the approaches worth prioritizing:

• Start with the no-gadgets modifier on Malta. The training camp level was specifically designed as a sandbox for experimenting with different approaches. Removing gadgets there teaches you what the melee system can carry on its own.
• Use the headshots-only modifier to learn enemy patrol patterns. Because you can't spray shots, you'll naturally slow down and observe more, which reveals patrol gaps useful in other runs.
• Revisit the Kensington level without a target approach in mind. The level designer confirmed multiple routes exist that most players won't find naturally. Go in without a plan and see what the architecture reveals.
• Check which suits and gadgets are TacSim-exclusive before deciding which modifiers to prioritize. Once the full reward list is available, you can plan which challenges to tackle first.

Modifiers change how each mission plays

Is TacSim enough to replace New Game+?

Honestly, it depends on what you wanted from a second playthrough. If the goal was to experience the story again with more knowledge of what's coming, TacSim won't satisfy that. The mode exists entirely outside the narrative.

If the goal was to get more out of the mission design, which is genuinely the stronger half of 007 First Light's structure, then TacSim is a reasonable substitute. The modifier system creates pressure that the base campaign rarely applies, and the reward loop gives you a concrete reason to keep going.
