It is laid out like a sideways "U". At each station, you can "grab <ingredient"> and it will start a fight. Each mob drops an item you can use to assemble a taco at the end of the "U". The menu on the will will let you know which ingredients you need and the further down you go in the menu, the harder the tacos get.
In most rooms, you can go "down" and enter a brief falling room before landing on the floor. There are multiple cockroaches on the floor. Once the cockroaches are dead, at the westernmost edge is a room with a grate you can break to enter a hidden room to the west. In there is a chihuahua. After killing the chihuahua, you can use "door" to leave the area.
Since the Lettuce (and every taco, since they all contain lettuce) can force you out of the room, you can potentially be sent down. It may be worthwhile to head down right off the bad and clear out the cockroaches, break the grate, and kill the chihuahua before you get started. It will also mean you can escape more quickly if you need to.
Each ingredient has a different abilities and tacos have the combined abilities of their ingredients:
- shell: bleed effect
- cheese: force unwield of weapon
- lettuce: force move to another room
- meat: -con debuff
- sour cream: regens itself (Death taco will get 4 lives with sour cream)
- guacamole: force remove of gear
- hot sauce: blinds
Recipes for each taco are:
- veggie taco: shell, lettuce, tomatoes
- cheesy taco: shell, lettuce, tomatoes, cheese
- meat taco: shell, lettuce, tomatoes, cheese, meat
- works taco: shell, lettuce, tomatoes, cheese, meat, sour cream, guacamole
- DEATH TACO: shell, lettuce, tomatoes, cheese, meat, sour cream, guacamole, hot sauce
After defeating any taco, you can 'push door' from assembly room. Otherwise, you can do go 'down' from any room. You'll fall for two rounds and then be on the floor where there will be a bunch of cockroaches. They're much smaller than any ingredient. After killing all of them, in the westmost room, you can 'break grate', kill the dog, and then use the 'door' to leave.
Each ingredient drops an item you need to assemble the final taco. Drops from the taco itself will depend on the current scaler. 91 is the break point for maximum awards
