Heavy Thoughts is a fun romp through thoughtfully dressed up Industrial and Hell modules. There is a light story line here. You can play this solo or with a friend as you stomp through some very fun wave events. Ammo is laid on pretty heavy and you'll have a full arsenal before you finish this map. Some of the weapons were just scattered about, which seemed out of place with how carefully everything else was set up. And I thought the power-ups could have been placed a bit more judiciously.
