I like it (especially the red-shirted Unstable Genius)!

Just a couple of problems:

1. The Smooty All-In-One has a max capacity of 2 people after upgrading. You can go without shelter, however.
2. The Multi-Purpose Prefab has a max space of 2 after upgrading -- but you can fix it by putting the Chemical Cuves into your Tom Custom (with upgrades)

Arm everybody and give everyone ammo (you'll run out soon enough).
Put your Welfare Specialist into an Eisen Suit so your Science Student can use it.
