## Questions & Answers

**Q: Does this include a code for the action block vehicle paint scheme in the halo infinite game?**
A: Unfortunately, no. I believe the mega construx have all stopped and discontinued the codes. I bought lots of different sets as i read they had codes, and sadly i did not get any codes from any of them

### ⭐⭐⭐⭐⭐ Muy bonito, con detalles pero pequeño
*by L***M on 9 January 2022*

Lo ocupe para obsequio, se tarda uno al rededor de dos horas a tres armándolo. Queda muy bonito pero es bastante pequeño, se necesitarían al rededor de 5 sets para armar el Halo completo. Para colección es perfecto
