Abandoned Laboratories

Abandoned Laboratories is a Deathtrap level.

Description
Some of the strongholds were built in the colossal vaults where the Trapmakers used to experiment with their first killing devices. Mystery shrouds those early days, and from the few remaining notes it seems that they had some truly strange ideas, like platforms that could trap you in a god's dream or sigils that could conjure thunderstorms. For reasons unknown they eventually abandoned these designs just as they left behind their laboratories. Ironically some of these places became forts where the swarms can relive the history of their previous defeats.

Tier 2
The Metamorpher Sentries fire in a tight angle. Kill the weakened monsters before they change back to their original shapes. Beware: transmorphed creatures move with a much greater speed!

Tier 3
Teleporting, rushing, cloaking monsters will try to overrun your defenses. You will have to fight with very limited resources. Salvage Recyclers and Enhancer Beacons will help you in the struggle.

Tier 4
This map only has Mechanical Tower slots and Mechanical Ground Trap slots, apart from some special traps unique to this map. Tip: keep an eye on the approaching waves, observe which creatures follow which lanes.
