Gundam Breaker is so appealing to Gundam fans because it really captures the feeling of building YOUR dream Gunpla in-game, earning and using parts from existing real life Gunpla kits! Bandai Namco have even stepped up the 'Build-A-Gundam' features in this sequel by adding 100 different pieces for each slot (head, arms, legs, body, etc.) which will ultimately allow up to 10,000,000,000 (yes, BILLION) kit bashing combinations. The only thing stopping you from putting GPB-04B BEARGGUY's head on every Gundam is your own imagination. What you equip isn't solely aesthetic either and can affect your performance greatly, as well as add abilities.
Gundam Breaker gameplay and combat is modeled after traditional hack n' slash games and Gundam Breaker 2 adopts many of the same features from the previous title, with improvements to make combat more fluid and fast. Gameplay types are divided into five different mission categories: Normal, Defense, Survival, Team Battle, and Arena Gain. Normal mode has players fight through different stages with a respawn mechanic, while Survival is similar but ends when your HP reaches zero. Defense has players defend a certain point against an onslaught of enemies. Team and Arena allow multiple players to team up and fight together.
