Arena Blaster

Arena Blaster is a playable ship added in the Relics of the Past DLC. It features unique gameplay, being unable to use bombs, but instead gaining access to an array of special active items. Its default weapon is the Peashooter.

Story
Arena Blaster is the 1st Visitor of the Facility. A developer has stated that, canonically, Arena Blaster didn't make it any further than the Maintenance System before being destroyed.

Gameplay
Arena Blaster is unable to use bombs, but gains access to special active items instead. A room containing a random active item, similar to those in which you find weapons, can be found on floors 1, 3, and 5 of the Facility. The necessity to create this room causes the layouts of those floors in a given seed to be very different for Arena Blaster compared to other characters. Active items can also be found in most places that you could find a bomb, but bomb pickups in room layouts will just be replaced with coffee.

Since they are unable to use bombs, Arena Blaster is able to expend charges to break walls in order to access shortcuts and secrets. This makes finding secrets trivial for Arena Blaster in comparison to its peers. The inability to use bombs also means some cartridges are removed or replaced. While Arena Blaster cannot use bombs conventionally to open shortcuts or secret rooms, using the Unstable Catalyst active item will do so as if you used a bomb, using no extra active charges.

Active items can serve a wide variety of different purposes, ranging from purely utility to purely combat. Note that all attacking actives will scale with the player's damage stat like weapons.

Charges
The player gains 1 charge per room of enemies cleared and 3 charges for collecting coffee, to a maximum of 6 charges. If you pick up coffee at full charge, you will Salvage the drink. You can also get the Capacity Upgrade to expand the limit to 12 charges. Upon picking up a new active item, the player's charge is set to 6 if it was less than 6 charge, but is not lowered if it was higher than 6 charge.
