Pros:

VERY detailed
Realistic lighting
Plenty of weapons
NO BUGS! Everything works as it should!

Cons:

Can be difficult with only one other player, but that just makes it more fun

Conclusion:

This is the most professional looking custom map for Contagion I've seen

Pros:

VERY detailed house
Realistic design, looks like it was taken from a floor-plan
Rain/storm/lighting effects are perfect
Custom textures?
Gives you a real sense of being alone

Cons:

Not enough weapons or items (esp. melee)
Difficult to move around in (small environment)

Conclusion:

This is an INCREDIBLE first map! Very challenging.
