Description
Boss Rush is a challenge map, which is only available through Sandbox mode. It is a modified version of Intermediate mode, while wave structure is completely overhauled parts of the modes it is based on, such as music, wave clear bonus or reward multiplier reductions remain the same as in Intermediate mode. Triumphing this challenge would reward the player with 150,
500 EXP,
4 and three Nukes. However, these rewards cannot be gotten as this map only appears in Sandbox mode.
