Ok. 2 easy examples how to chase down or kill someone.

1. Hit the upper prox of the ship. Why? Either the enemy ship moves in direction of wall, so it`s easy to hit another bomb or the enemy ship moves up and gets a hard direct hit of the bomb you aimed at his prox. (you should and can combine with bullets)

2. Actually the same, just with 2 ships chasing 1 in open space. You can imagine a similar picture chasing 4on1.
