Spreading the railgun gospel!
The Railgun is so strong and fun for bots I love it, it is such a good weapon to peak shot with so you'll need to find a good cover, I'm also strafing like a manic to reduce my chances of getting hit which works 80% of the time including squids, it seems like the projectiles enemies tend to shoot where you are going so when you strafe/move/run back and forth they will miss.
