Pick it if…
- you want to fight, blast and test your reflexes
- you have time for an evening or two (roughly 1–6 hours to see it through)
- you've played the Genesis hits and want something less obvious
Maybe skip it if…
- you prefer slow, thoughtful games over reflex tests
- you are looking for something to play with friends
What playing Onslaught 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.
