I really like the update, good job. The SMG and its reloading mechanic are great. Personally, I'd just increase the trigger volume for snapping the magazine in place a little bit so it's easier to reload while you're under fire. Even if the magazine does a little "teleporting" then, I think the tradeoff is worth it since this seems to become more of an arcade-like title rather than having emphasis on realism like in H3VR. The dropped magazines could also use a larger trigger to make them easier to pick up. The robots are awesome but I'd like to have some kind of sound when they have you in their view and get ready to fire, so you could dodge their projectiles at the last second when they sneak up from behind. Maybe that would get annoying at some point but I think it's worth a try to see if it improves gameplay. Minimap was much needed and is implemented perfectly. The new enemy behaviour really adds a lot to gameplay. I love how some soldiers duck right away when you encounter them, so it's not always easy to get a quick headshot anymore. The fact that they have senses now and help each other is great and sometimes creates very stressful situations where they "swarm" you from all sides but I still think the difficulty is appropriate. HUD is also good.
The only things I'd like to see in the next update other than more complex levels are options to change the vertical position and rotation of the guns, like you can do in Space Pirate Trainer (at least rotation).
I'm very happy with this update already and looking forward to the second part.
