What playing Gain Ground is like
Action games test reflexes and nerve. Expect fast enemies, tight controls and stages you clear by reacting quickly and learning enemy patterns.
Tip for newcomers: Retro action games are often short but tough. Treat early deaths as practice runs; every attempt teaches you where the next threat comes from.
