@LordDarias Thanks, I only played the single player so I can attest to this being worthwhile for it alone. There's no overarching story connecting the missions or anything which might impact your enjoyment if you like what you're doing to have some wider context, but I find this interesting in the sense that it's like a playable anthology series since (like I mentioned) they put so much effort into the storytelling of each individual level anyway. I assume there’s some way to get the multiplayer working on modern systems since Chaos Theory's online modes also used Gamespy and there are workarounds for that, but I've no experience with that kind of thing myself.
