Time attack mode grants infinite lives and has rings placed in-between battles. Survival mode has only three lives and has no rings whatsoever.

Well done hack

Reviewed By: diablo666 on 03 Sep 2021

In short, this hack is Boss Rush. We took the Bosses from the 1st and 2nd parts. But, however, they are competently ported and distributed according to complexity.

There are two modes in the game: “Time Attack” and “Survival”. And both modes are good. One with infinite lives, because the task is “to destroy them faster than everyone else”, the other - three lives and “destroy everyone without dying himself”. In each category in the final - you are given a rank. The better the game is played, the higher it is.

This hack is suitable both in a SOLO game, and to arrange a COMPETITION.
