It's quite apparent before you even open the box that this is a substantial Lego project. With almost 800 individual pieces, it will take even the most experienced modeller the best part of 2 hours to complete. However, the build experience is every bit as fun as the finished article. There are plenty of movable parts in this design, ranging from traps to tricks, creatures and a half-track car. Some of the features are very imaginative like the hinges stairs with creepy crawlies inside, the trapdoor which drops blocks of stone on the unwary adventurer and a sarcophagus which will suddenly appear from a walled-up tomb.
The only real disappointment is that the blow-moulded base already has a good part of the pyramid pre-formed in it, which effectively means that space for moving figures around inside the finished building isn't quite as extensive as it otherwise could have been, and the moulded base itself, whilst being up to the job, is a tad flimsier than I would have liked to see.
Other than that, this is a really super model and should provide hours of fun both in the construction and subsequent tomb-raiding adventures. It's perfect for two to play together - one being the adventurers and the other the mummy and monsters.
Super fun. Recommended.
