Scaling Bonuses For Long Runs

[-BOLM-]

Each time 5 waves of defence, an interception wave is completed, 5 minute of survival pass, etc., a bonus should be given. 

The way it works:

Bonuses stack up; for example, after 5 waves of defence, when the player decides to continue, (s)he picks a bonus given: more power strenght, weapon damage, ability efficiency, hp, whatever they want to stack more. 

This way players will be able to keep going further into fighting high level enemies (above lvl 150) with stacking bonuses. The longer you go on for, the stronger the enemies, but so are you.
