You get a free center back upgrade that asks for almost no effort. Bone Builder dropped quietly inside the Ultimate Scream promo and turns a cheap 81 or below CB into a ball playing defender with real passing numbers. Registration stays open until November 7 at 18:00 UTC and you keep until November 14 at 18:00 UTC to finish the matches. The evolution is free, no coins and no FC Points, so the only thing you spend is a few games. Do it now, because the best budget CBs will not stay cheap once this guide spreads.
FC 27 Bone Builder Evolution Requirements You Must Hit
Start by checking the gate. Bone Builder only accepts a pure center back, and the card must sit at 81 or below with 84 pace or less, seven or fewer PlayStyles and zero PlayStyle+. Miss any one line and the evo will not let the card in, so confirm on the evolution screen before you commit a player. Full backs with a secondary CB position are excluded, the slot reads primary CB only.
| Rule | Limit |
|---|---|
| Position | CB only |
| Rating | Max 81 |
| Pace | Max 84 |
| PlayStyles | Max 7 |
| PlayStyle+ | Max 0 |
FC 27 Bone Builder Evolution Upgrade Path, Level by Level
Bone Builder runs three levels, and every level rewards passing and composure over raw defending. The headline finish pushes Short Passing and Long Passing to 85, adds the Pinged Pass PlayStyle and lifts Weak Foot to three stars. The table below shows the full spread by level and the match each one needs.
| Level | Top boosts | Match objective |
|---|---|---|
| 1 | +7 to 82, Short Pass 85, Ball Control 83, Strength 84, Agility 74, Def. Aware 83 | Play 2 matches |
| 2 | Weak Foot 3, Pinged Pass, Long Pass 85, Dribbling 80, Balance 74, Stand Tackle 83 | Play 1 match |
| 3 | Vision 80, Curve 78, Composure 84, Reactions 81, Jumping 80 | Win 1 match |
Read the path as a passer build. Short Passing and Long Passing both land at 85, Vision reaches 80 and Curve 78, so your CB can step into midfield and switch the play. Composure at 84 and three star Weak Foot mean he keeps the ball under press. The defensive side still climbs, Stand Tackle 83 and Def. Aware 83, but the card clearly wants to build from the back, not just sit deep and clear.
Best Center Backs for the FC 27 Bone Builder Evolution
Which card you feed in decides the value. Community trackers rank Marco Rente of FC Groningen as the top finisher, an 80 rated CB who ends as an 82 Deep Lying Playmaker with the highest Meta Score in the pool. The budget route is where Bone Builder shines, because several 81 or below CBs cost under 1,200 coins. All prices below are predicted market values from community trackers, not EA figures, since EA does not publish card prices.
| Player | Club | Start | Finish | Predicted price |
|---|---|---|---|---|
| Marco Rente | FC Groningen | 80 CB | 82 CDM | Tracker top pick |
| Oumar Solet | Udinese | 78 CB | 82 | 1,100 / 850 PC |
| Ousmane Diomande | Nott'm Forest | 81 CB | 82 | 1,000 / 950 PC |
| Pubill | Atletico Madrid | 81 CB | 82 | 950 |
| Kevin Diks | M'gladbach | 77 CB | 82 | 1,200 |
Rente is the safe answer if you want the best end card and do not mind a lower league name on the shirt.
Solet and Diomande give you a bigger club for roughly the same coin outlay, and both clear the pace and PlayStyle gates with room to spare.
Pubill at 950 is the cheapest 81 starter, while Kevin Diks is the lowest rated base at 77, which leaves the most room for the +7 rating bump. Grab these now, because cheap eligible CBs climb once this guide spreads.
How to Finish the FC 27 Bone Builder Evolution Fast
The objectives are light. Level 1 needs two played matches, Level 2 needs one played match, and Level 3 needs one win. Any single game counts toward only one level, so you need at least four matches total, and the win can come from the same modes as the played games. Set the evolution to Active in My Evolutions before you kick off, or the match will not register your progress.
- Squad Battles, Semi-Pro or higher, the easiest lane for the win
- Rush, counts with your active EVO player on the pitch
- Rivals, any division match works
- Champions, weekend league games qualify
- Live Events, themed matches also count
You can grind all four in one Squad Battles session on Semi-Pro if you want the safe route, and the required win lands fastest there too. Bring the EVO player on at kickoff, let him play the match, and the level claims on the final whistle. No clean sheets, no goal totals, no extra conditions beyond using the card.
FC 27 Bone Builder Evolution End Date and Deadlines
Two clocks matter. Registration closes November 7 at 18:00 UTC, the last moment you can start the evo. Completion closes November 14 at 18:00 UTC, the last moment you can finish the matches. Miss the first clock and you never start. Miss the second and you keep the levels you already claimed but lose the rest. The window is generous, so do not wait while the cheap CBs sell out from under you.
Bone Builder is a free Ultimate Scream CB evo that builds a budget 81 or below defender into an 82 ball playing passer, and you have until November 14 at 18:00 UTC to finish it.
