Yeah, I’ve seen a few that hit the mark. There’s that military‑grade VR platform that simulates urban combat with full-body haptics, and then the gamer‑centric ones that let you call in team orders and react to enemy AI. I’ve used the paintball version before – it forces you to lock onto objectives and use cover like in real life. If you’re tinkering with your own, focus on accurate physics, realistic sound cues, and a solid communication system. That’s what turns a demo into a training tool. Keep it tight, keep it realistic.
