STORY In the near future, a paradigm-shifting scientific discovery looms over the world, promising radical new technologies. The world’s superpowers realize they could have the power to destroy the global financial system, wipe out entire countries or even gain access to immortality.

Your objective is to ensure that it is your nation that reaps the benefits of Sigma Theory before anyone else.

Field operations: Direct the kidnapping of your targets during gripping pursuits through the world’s greatest cities. Discretion or direct confrontation, your agent’s life is in your hands.

Verdict
The clearest difference is in-app purchases: Pacific Fire at none against Sigma Theory's 7. Pacific Fire also leads on review sentiment (87% vs 58%) and ratings volume (152 vs 8). Sigma Theory's advantage is update cadence (fortnightly vs every 6 weeks) and iOS requirement (13.0 vs 15.6). On ads, monetization model and device support there is nothing between them.
