I'd say this is like a starter set that has 229 peices. This set has a Generator, training area (where Captain America, Hawkeye, and Agent Coulson are), weapons rack, and a Micro-scale Helicarrier.
The Weapons rack is similar to the one in the Polybag but is bigger. It's equipped with Captain America's shield, a walkie talkie, binoculars, fire extinguisher, handcuffs, a laser blaster, and 3 pistols. The pistols are different because I didn't like the ones on LDD so I used Nozzle pieces instead to give it that look of real pistols from the movie.
Agent Coulson is using the blaster from the movie and the upcoming lego marvel videogame. He is testing the weapon on a wall with a dummy of Loki. The wall was supposed to have stickers of blasts left behind from the weapon.
