beta 5.0 is the long-awaited, exciting, stable build which stands as a precursor to release 1.0.

so far, the game has most core features like

-a handful of different weapons 

-mystery box

-upgraded weapons

-powerups

-perks

-crawlers

-boss rounds (jellyfish)

-different areas

-wonderweapon

at this point, the game is basically CoD zombies. all that's left now is to do some polish and work on level creation.
