In the Gradius series of games (which Life Force is one of), you get these things called Options, which are kind of like little invincible drone ships that follow you everywhere.
But, lose concentration for a moment, and your ship explodes, costing you all your powerups. But you might notice that your Options just kind of slowly drift off to the rear edge of the screen.
Which means all you have to do is to swoop in and grab them, and you can immediately double or triple your firepower again!
Which will come in handy during some of those boss fights.
