I made this with the beta because I was stupid, it doesn't even use beta stuff. I will release fully once the next stable is released. I'll probably change some more stuff before then too, based on your feedback. Until then, check out what I got if you have the beta.
The Apocalypse box is your key to surviving the end of the world! Complete with running water, an electric system, a labrotory, a hospital, training facilities, and armoury, and one of the best sheild system ever, you can survive in style! https://powdertoy.co.uk/Browse/View.html?ID=359842
Some more changes. Improved pumps, gyms, and shields. Can survive one screen fill with thunder with pretty much no damage. Can survive a second with only shields damaged. Can pretty much survive a third with only minor interior damage.
triple post ftw Nice save. Quite slow for all the sand. Bomb drills straight through, but any other is impossible 'cause the PUMP can't melt nor break.
Hey, my triple post is well within the rules. You have to wait at least a day, and have changed something. EDIT: Wait, PUMP doesn't break? Well, that's awful. I need to use something else cause thats kinda cheating.
