Pros:

Excellent design.
Excellent new props, music and voices.
Good ammo balance.
Scavenge part, very well implemented in the continuity of the campaign.
Tons of fun.
After all, it's our favorite archaeologist.

Cons:

Short.
I was expecting more deadly, Indy-style traps.
Bots will inevitably trigger all the touchplates.
I know it's a rendition of a ride, so the "hallway effect" is normal, but still the maps feel a little bit too much linear.

Conclusion:

Short and sweet. Recommended. Even if it's for L4D2.
