Viruses:

For some reason, viruses were being "cured" just a bit too fast. I lowered the rate which a virus advanced through stages. I also fixed vaccines; they now actually cure viruses as well as providing immunity to any further infection. 


Metroids:
     The beginning of my Metroid ranching phase; Metroids may now, theoretically, be tamed to an extent. Baby Metroids are suceptible to simulated discipline, meaning if you beat them over the head with a toolbox for trying to eat your fellow scientists they will probably get the message. This also works when you're trying to wrestle a metroid off of someone's head. Additionally, they may also identify who the people who feed them are and in a situation where they have to fight to defend themselves or eat, they will spare their "friends". This is a pretty big AI change, so if you see any bugs please report them immediately!

     Metroids can also "vent-crawl" like monkies, but fully-grown adults are too big to do this. NPC Metroids will never vent-crawl. 


Weapons/Guns:
     A lot of you are going to like this one; you can no longer shoot yourself with your own gun! This happens sometimes when the game lags up for a bit, but no more!

     Additionally, you can now shoot people who are on the ground simply by clicking them. I can only imagine how easy this will make being an officer (or traitor/syndicate) now. This applies to both handheld guns and mecha weapon installments.


Xenobiology:
     Scientists now, hopefully, have proper Xenobio access. Metroid dissection has been slightly changed; you can extract Metroid cores from dead Metroids no matter where you're aiming. You will not see me talk about metroid cores anymore because they're a secret. I haven't done anything with them yet, however.
