I was bored the other day, so I decided I'd make a server and practice my building techniques. I came up with this blocade/bunker for one of the tunnels in sf_conduit, it has a couple nice features.
As you can see there is a step up to the slit in the wall acting as the bunker part, its not extremly hard to toss a nade into the bunker but it makes the enemy calculate the throw a little longer and of course it gives you pretty decent cover from enemy fire.
This is what the enemy sees.
Above the ramp, near the half way point I put a small wall to make it harder for nades to make it in threw the side, it hits the top part of the wall and rolls down the ramp into a nade catcher at the bottom.
Better look of the nade catcher.
There are still a few problems with my design, like the fact that it is somewhat expensive to build because it uses around 15 blocks and that it takes me about 250 seconds to build, hopefully ill get better at that part, but besides that, the enemy has a real hard time getting past, in the furture i want to incorporate some sort of system that will allow me to drop a nade over to the enemy side so I can quickly eleminate enemy engeneers.
Thats all, tell me what you think.
