This idea came to me just now after reading a post about suicide bombing module.
Anyway the idea is have every ship have in game have warp core detonation capability,
The damage output would vary depending on ship hull type, frigates would have a small area off effect and also less damage output than a battleship etc. Also skill for warp detonation would need to be trained to improve output and area of effect.
So the point of this would be if you know your gonna die potentially you might be able to take some people with you.
Also you would not be able to detonate the core unless you are have 25% hull left.
This is just a basic idea so feel free to improve add ideas
