Tower! Simulator 3: KSEA Airport

The KSEA Airport DLC for Tower! Simulator 3 was developed and published by FeelThere, and it was released on 1 May 2025, as part of the studio’s ongoing schedule of airport add‑ons for the PC version of the game.

The DLC offers a detailed simulation of Seattle–Tacoma International Airport (KSEA), the primary international airport serving Seattle and Tacoma, Washington. In‑game, players can manage operations across the airport’s infrastructure — KSEA in the simulation features over 50 custom‑modelled buildings, a full ground‑polygon layout, realistic taxi signs and 3‑D taxi lights that align properly with runway and taxiway markings, runway‑approach lighting, and realistic background scenery based on real‑world mapping data. The airport includes multiple parallel runways, four concourses with 115 gates plus two satellite terminals, offering a large, busy‑hub environment with substantial traffic density and operational complexity.

In promotion, the DLC was presented as a major U.S. hub addition to Tower! Simulator 3’s airport portfolio — drawing attention to the airport’s status as one of the busiest on the U.S. West Coast, its complex terminal and runway layout, and the immersive realism of its scenery and ground‑operation modelling. The marketing underscored KSEA’s significance in the region, its heavy traffic volume, and the challenge and depth it offers for air‑traffic control simulation enthusiasts.

Upon release, the KSEA DLC had a small number of user reviews (three at the time), which meant overall community feedback was limited and no clear consensus had formed. Given the modest review base, reception remains somewhat mixed or uncertain. Nonetheless, for players interested in controlling a busy and realistic U.S. airport — balancing runway operations, heavy traffic, and complex ground logistics — KSEA stands out as one of the more ambitious and feature-rich expansions for Tower! Simulator 3.
