The Unconventional Weapons in my game are Mass Points and Dimension Decreaser. Now Mass Points can be used to destroy solar systems. When a civilization loses all of its solar systems and its spaceships, it disappears.

The Mass Points can travel as fast as light (at the speed of 300,000 km/s). As we know, the kinetic energy of a moving object is equal to 1/2(m * v2), so Mass Points, of which the v is pretty large, has a considerable energy even it’s only several kilograms in weight and as small as several metres in radius. That’s why they’re ‘Points’.

The next is Dimension Decreaser. I’ll soon talk about it, at least after implementing it in the game

PS If you have a better name for this I’d be glad to take suggestions.
