IO Interactive Plans Ongoing TacSim Content for 007: First Light After Launch Day

007: First Light released today, May 27, on PC, PlayStation 5, and Xbox Series S/X to what IO Interactive chief development officer Véronique Lallier calls just the beginning. The game has arrived at high score reviews, with Eurogamer's critic writing that IO delivers the sharpest, most entertaining script in the triple-A space since Eidos' Guardians of the Galaxy, and that the game keeps players on side even in its weakest moments through sheer force of personality.

Some reviewers have already flagged it as a contender for Game of the Year. The one recurring criticism is replayability — 007: First Light is a linear, scripted action game, which sits at odds with the sandbox structure IO used for Hitman. IO says it has a plan for that.

The studio's answer is TacSim, short for Immersive Agent Training and Tactical Simulator. It is an optional mode accessible from the main menu or from Q's basement at specific points in the story, overseen by a character named Selena Tan, who presents a rotating list of challenges. TacSim remixes existing levels from the campaign with different rules, conditions, and in some cases entirely new combat encounters built into spaces that had none in the main game. Most TacSim missions unlock only after completing the campaign.

The three mission categories within TacSim scale in difficulty across a structured path:

• Training — introductory challenges that explain mechanics and let players practice before harder iterations.
• Test — mid-tier missions that apply the trained skills under stricter or modified conditions.
• Showdown — the final, hardest version of each challenge, designed as the definitive completion of that TacSim arc.

As players work through missions, they earn Intel, a currency spent on unlocking suits, gadgets, weapons, and upgrades to carry into subsequent TacSim runs. Clearance level tracks overall TacSim progress and gates certain Intel purchases — the Missile Pen, for example, requires Clearance level 15. IO has confirmed that TacSim will receive additional content updates after launch, including race tracks built around the Valhalla spy car.

Senior combat designer Tom Marcham described TacSim's scope in a recent interview, saying there might be encounters placed in areas that had no combat in the original campaign, with the studio deliberately reusing space rather than just adding difficulty modifiers to existing fights.

"TacSim is basically a space in which we can remix our levels."

Lallier connected TacSim explicitly to Hitman's post-launch model, which IO has sustained for over a decade under the World of Assassination umbrella.

"It's something we've done very successfully with Hitman. We have TacSim content that will be made available after launch, and there will be a roadmap of content. Because for us, the way we see things is: launching the game is just the beginning, and it's important for us to learn and listen to the feedback of the players and everybody and see, okay, how can we do it better? What should we do more? What should we do less?"

— Véronique Lallier

Lallier was also careful to separate TacSim from the Hitman comparison in terms of what the mode can realistically deliver. Hitman's sandbox structure makes repetition feel native to the game. 007: First Light is narrative-driven, which changes what post-campaign content needs to accomplish. TacSim is not trying to simulate the open-ended loop of Hitman — it is trying to give players somewhere to go once the story is finished, with new rules and escalating conditions rather than freely replayable assassination targets.

"It's completely different from Hitman and that's something very important to say. Hitman is sandbox and by nature feels more open to repetition. This one is more narrative driven, so once you've done the story, what else can you do? And that's what we're trying to do with TacSim. There is definitely a desire for us to continue to make things evolve."

— Véronique Lallier

I think the distinction Lallier draws matters more than it might look at first. A linear game with good writing does not need to become a sandbox to have longevity — it needs structured reasons to return, and TacSim at least provides a mechanical framework for that. Whether the content roadmap delivers enough variety to hold players past the initial wave is a question the next few months will answer.

Marcham also said the studio hopes speedrunning communities will pick up TacSim's leaderboard challenges and compete there. That is a plausible secondary audience for this kind of mode — leaderboard-driven players who care less about narrative and more about optimizing routes through constrained scenarios.

I know IO has made this work before with Hitman, where Elusive Targets and escalation contracts kept a dedicated player base engaged for years after launch. The question is whether a game built around a single authored story can sustain that same community relationship. First Light's critical reception gives it a strong start, but the TacSim roadmap is what will determine whether that audience sticks around.

007: First Light is available now on PC, PlayStation 5, and Xbox Series S/X.
