Hey, I recorded a playthrough of your map that you can watch here:
I really liked the theme of you having to escape a prison and fight back with your rebel allies. I enjoyed the combat and utilizing the oildrum for the heavy-duty wooden beams. The only real thing that I found annoying was having to stack three boxes on top of one another. That area is a straight line with a wall that does electric damage to the player. If that side of the electric fence didn’t do any damage, then I probably wouldn’t have become as frustrated as I was wobbling back and forth on top of those crates. I also got confused on my first playthrough with the ending. That part of the map with the combine shield is really open so it looked like an exit to me. However, when all those combine came rushing in at the end I thought it was a scripted death until Alyx died and restarted the level. I didn’t notice the huge hole with rebels coming out to fight with me since I was facing the enemy forward. On the second playthrough I just ran for it to escape because I didn’t want to risk Alyx’s death and restart the level again. It’s a cool ending to a fun map but maybe Alyx could’ve pathed towards the back barricade near where the rebel hole was going to be before the combine started mass spawning. That way the player could be hinted to follow suit and reduce the chance of a reset. Regardless, I still really enjoyed playing this map. Great work!
