I know this is late and all. I don't really like playing as SCP, but I always prefer 049 or 096. They're your best offensive SCPs. If you play well with that is. They serve as the bread and butter. Rivaling that of 939. 049 is effective when it comes to infecting people and turning them into zombies. 096 is your kind of SCP if you wanna clear out an entire squadron of MTF or Chaos. Or just break down doors for a clear pathway or something.
