Hi guys,
This update I've added a variety of new gameplay mechanics, plus altered most of the levels. For this reason nows a good time to replay the game! I've reset the save file so you can start fresh.
New Features
You can now shoot pipes to dispatch enemies in a steamy death
You can now shoot overhead objects to drop onto groups of enemies
You can now shoot explosive barrels, blow up the S.C.U.M!
Any problems/feedback let me know on the games steam forums,
Enjoy!
