Striker is a science-fiction role-playing game that can be played as a space opera, or fit within any noir-style cyberpunk-ish adventure. It supports narrative and combative styles with an even grace, so you can sci fi any way and any how.
The main adventuring scenario has a rich lore. Read it in the Strikerpedia.
It hard to appreciate how well all of this works, until you're playing. There will just be a point when the lights go on, and you realise what you can do with all this (I've seen it happen with new players).
Over 200 hours of play testing has produced a system that simply works!
Yes, it might look like a standard d20 adaption, but standard, it is not.
It's all here to make high tech and space feel real, and offer players the maximum agency in their actions and overall story.
Character progression and development, while mediated by levels is not a track, but a kind of branching out, you choose which direction your character goes in. So every character is unique, and if you want that special ability, you can have it, by just putting in the work. No class features are going to stop you.
The World of Striker is vast and detailed, so vast and so detailed that it doesn't fit into the Core Rulebook, but there is the Strikerpedia, and I continue to push out articles that discuss some areas, and soon I will have released some epic adventures that will start to bring that world out.
