How many automatic weapons do you get in that game?

3, i think...

The fight against Both Shades is harder, my favourite bit is the amazing leaps wesker makes! and how hard he can hit the ground after falling too!

Killing Ivan was one of the easiest battles in the game for me. just pump rounds into his face all day. SMG HP was my weapon of choice on Hard (although later I found the Autopistol to work much better). he dies pretty ****in quick like that. Killing two at the same time was even easier. grenades and ground shots with explosive weapons between them, while they're standing next to each other in the tunnel, just after leaving the central lift area. owned. even easier once you have unlimited ammo.

you only get three in the game: SMG, Autopistol, and SMG HP
The Autopistol is my fav, simply because it ROF is higher than the SMG HP, and therefore takes more damage, even though its power is lower.
