As monsters spread across the world, the government gathered students with dimensional powers and established the Tactical Academy.

Combine their abilities, weapons, and parts to lead a three-person squad. • Survive the waves of monsters. • Train distinctive students and build your squad. • Find powerful combinations, overcome each battle, and protect the city. A two-person indie game. PROTOCOL: Zero Rift

Verdict

The call

The clearest difference is ads: しんけん魁!! at none against PROTOCOL's shown. しんけん魁!! also leads on iOS requirement (13.0 vs 15.0). PROTOCOL's advantage is update cadence (every 3 days vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.
