Zombie Party is a retro rampage of fun and over-the-top action, while still giving the players a deep and engaging Action-RPG Rogue-like experience! Go on a time traveling adventure, or delve deep into procedural dungeons full of gold, loot, and secrets! Unforgiving boss fights that challenge the players skills and abilities! Upgrade your guns with loads of gun mods and artifacts, find magic spell runes, potions, items, melee weapons, explore 10+ unique biomes each with its own enemies and bosses, unlock 50 characters to play as, discover 150+ unique guns and weapons, launch teddy bears that explode into fire, blow up your friends with heat-seeking missiles, and get to the final zone and try to kill the Dance King.
Step 1: First Adventure Playthrough
When you begin the game, you will be given a few default characters to play with. It doesn't matter who you choose, so pick whoever you like and start a play of Adventure mode. Zombie Party is split into seven different levels, and if you manage to beat all of them, the game will continue cycling through the levels and become harder. My first play I made it all the way to the final level and died. Make sure you save at least 350 Gold (so have that available at all times in case you die earlier than I did).
Step 2: Buy Shadow and Get 10 Million Points
Now that you are familiar with how the game works, here's how to make it an absolute cake walk: with the money you saved in Step 1, purchase the character Shadow. If you have additional money, upgrade his Damage and Fire Rate. You will be using his basic Shurikens for the rest of the achievements. This sound silly in a game with so many different guns, but it truly makes the game pathetically easy. See "Sick Score!" for tips.
Step 3: Grind 25k Gold
There are two ways you can go about getting this much money in your bank account. The first is to simply repeat adventure mode over and over. The other option is to play the slot machine from the main menu options. See "Filthy Rich!" for tips.
