Tips/Notes
To get this achievement you have to build all 9 combo items meaning you can't pick it up from jed (Pitchfork Shotgun) or buy the item from the pawn shop (eletric rake, Drill bucket).
DarkLordRaptor Says this achivement can be done on multi playthroughs
Alita360 has told me that you have to actually build the items buying them at the shop does not count towards the achievement

Requires you to collect to parts to a combo weapon, head to the work bench and combine the items.

4. Air Horn - Orange Cone (streets or department store) + Spray Can (junkyard)

8. Chainsaw Paddle - Kayak Paddle (found on a ledge on the right side of the police station) + Chainsaw (found in hardware store)

9. Boomstick - Pitchfork (found in hardware store) + Shotgun (found in hunting store)

A guide made by me, Mr WAFFLES hope this helps, comment if any thing is wrong. You will also get an achievement for making one item

This one requires you to create one of every combo weapon found in the game. Below are the weapons and the items used to create them. Note that this doesn't require you to obtain all the Combo Cards, you just have to create all the weapons.

-Paddlesaw - A single Paddle is located outside the first building opposite the Gas Sation, next to the police station and near the white van that the pawnshop owner is found on. Chainsaws are available in the Big Buck Hardware store.

-Beer Hat - Beer is a common item, but there is only one Construction Hat in Still Creek, and it is on the roof to the east of Bob's Fish 'n Hunt. Go into the alley to the south of the shop, jump onto the dumpster, from there jump west to the air conditioner, from there west to the awning, go north around the roof fencing, then climb onto the roof and head east. Jump the western gap towards the fire escape, but do not jump the railing - jump north onto the air conditioner, then onto the target roof.

-Air Horn - There is a Purple Spray Paint in Still Creek, and it is on the roof of Brockett Gas Station, accessible via the storage room in the rear of the building. There is also a Green Spray Paint can in the alley that leads to the back door of the Sheriff's Office. Pylons can be found in the alley east of the Maintenance Room behind Uncle Bill's Department Store, or in the Quarantine Zone.

-Spiked Bat - Both the Baseball Bat and the Box of Nails are common items that can be found in the Safe House.

-Electric Rake - Leaf Rakes are available in the Big Buck Hardware store. There is a single Battery behind the Still Creek Movie Theater, not to the south but to the north; starting from Ed's Friendly Barber Shop, head east and go north up the second alley. It turns west, and the battery is on top of a dumpster. There will usually be a few zombies back here too.

-Drill Bucket - Both Buckets and Power Drills are common items that can be found in the Safe House.

-IED - Both the Propane Tank and the Box of Nails are common items that can be found in the Safe House.

-Molotov - Both Newspapers and Whiskey are common items. Newspapers are easily found by smashing Newspaper Boxes.

-Boomstick - Pitchforks are available in the Big Buck Hardware store. Shotguns, however, are pretty much the trickiest collectibles in Still Creek; two are available in Bob's Fish 'n Hunt, one is available in the Sheriff's Office. Both require some creative maneuvering, as the front doors of both buildings are initially locked; To enter Bob's Fish 'n Hunt, head west from where you found the Construction Hat, drop down onto the awning on the north side of the building, then jump west onto the roof of Bob's Fish 'n Hunt - do NOT jump onto the awning of Bob's Fish 'n Hunt. There is a trap door on the roof, with "Bob's Down Here" written above it. The Sheriff's Office is accessible by jumping onto the dumpster to the west of the Grumpy Dog Bowling Alley, then jumping from there over the fence to the south. Follow the alley all the way west into the back door of the Sheriff's Office, then head upstairs to find a shotgun on the desk.

A bigger taste... - 10G (Original Achievement)

Difficulty: 2/10

To get this Achievement, you need to create all 9 of the combo weapons in the game.

Spiked Bat - In the Safehouse where Katey is, you can pick up both the Baseball Bat, and the Box of Nails, then use them both on the nearby workbench to combine them into a Spiked Bat.

Drill Bucket - In the Safehouse where Katey is, you can find a Drill on a shelf, and a few Buckets outside the building where you save. Simply use them both on the workbench near Katey to get the Drill Bucket.

I. E. D. - In the Safehouse where Katey is, you can find a Box of Nails, and a Propane Tank nearby and use them on the workbench to create the I. E. D.

Beer Hat - Go to the Pub/Bar and grab one of the many bottle of Beer lying around. Afterwards you will have to find the one Construction Hat in the game which is located on a rooftop near the Hotel. If you can get onto the roof where Bob is, you can maneuver across the rooftops until you find it (the position is hard to explain, just thoroughly explore each rooftop)

Molotov - Use your Map to find the Department Store (next door to the Pub/Bar, and you will find a bottle of Whiskey in the cooler section near the Orange Juice and Milk. After grabbing a bottle, simply smash a Newspaper Dispenser in the streets to grab a Newspaper and combine them at the nearest Workbench to make a Molotov.

Boomstick - Open your Map and head to the Bar/Pub, once inside you will find a Pitchfork in one of the corners laying on the ground. Grab that and after you have unlocked the door to the Hunting Shop (See the Locksmith Achievement) across the street, go inside and break the glass on the case holding the Shotguns and grab one. Use these together on the Workbench in the Maintenance Room behind the Department Store to make the Boomstick.

Paddlesaw - From the Safehouse, head out to where the zombies are, and straight across the road is a boarded up Sports Store, outside the store on the right side you will find a Paddle. From here run down the road past the Pawn Shop and Bowling Alley until you see a Fountain made out of car tires on the right. In one of the nearby buildings you will find a Chainsaw. Once you grab one, head back outside and next door you will find a small shed-looking Maintenance Room with a Workbench where you can combine these two to make the ridiculously fun Paddlesaw.

Electric Rake - In the same building where the Chainsaw was you can find a Leaf Rake on the ground. After grabbing that, you can run down the road towards the Quarantine Zone where the cars are blockaded and take the last possible left just before it. You will run down a small alley and take a short left at the end to find a dumpster with a Battery sitting on top of it. Grab the Battery and return to the Maintenance Room next door to the building where you got the Leaf Rake to combine them on the Workbench and make an Electric Rake.

Air Horn - In the Safehouse where Katey is, you can walk into the store section of the building and enter the doorway that isn't blocked off to find the ladder leading to the roof. Once up top, you can find a Purple Spray Can on top of an Air Vent. From here use your map (Back Button) and head to the Department Store (you may need to hover the cursor over buildings to see their names, this store is next door to the Bar/Pub). Once you arrive go around the right side to find a few Pylons. Behind the Department Store is the entrance to a Maintenance Room with a Workbench where you can use these two items to make the Air Horn.
