Overcharge costs a whooping 120 antimatter and what does it? It gives a minor bonus to the other ability's effects (none in the case of scattershot).
I like the ability snipe the most, I'm sure explosive shot is better in fleet vs fleet battles because of the damaging effect. But the ability to focus fire one ship/building is extremely nice to have early in the game. You can snipe capital ships, ship factories and starbases.
Snipe cost 90 antimatter, and does 3k damage. With overcharge activated it does 4k damage. However why would I spend 210 antimatter for 4k damage when I can do 6k damage with 180 antimatter? Am I missing something or is the overcharge ability useless?
