If you like killing turrets, you should check out this chamber I made: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1705296912

Some fun turret dodging and zapping in the mid-game, and a pretty intense battle at the end.

(in response to below comment) Turret trolling is my favourite thing to do. As for the map in general, it's a learning curve for me, as I'm just trying to figure out what works and what doesn't.

Oh, and if anybody reads this that likes Alien: Isolation, can you please figure out how to create an Alien: Isolation portal map and then send it to me? Am a huge fan of that game, and I really want to see Portal played on Sevastopol with the alien etc right on your tail.

As far as I could tell, the speed get isn't needed, since you can make the jump just by falling and portaling in the jump room. I think this could be fixed by removing the portable ceiling (and maybe also the portable walls) in the jump room.

Destroying turrets is always fun!
