Blockout and Design
The first half of the project was spent blocking out the entire level using simple shapes. I combined both inside and outside areas for a more varied environment. The flag that was going to be easier to defend, I put in the inside area. The flag that was supposed to be harder to defend I put outside where it was more clearly visible.
I put the spawn area of the "attacking" team at a higher elevation, as moving downward tends to be easier/faster than moving upwards. The spawn area of the "defending" team was put behind the inside area, in a way which incentivized slower movement and staying closer to their own flag.
Placing weapon pickups was one of the trickiest parts, as some weapons were powerful enough to immediately throw off the balance between the teams. Placing them in a way which kept the balance of the level required a lot of playtesting and tweaking.
One thing that I would do differently if I were to redo this level, is to increase the distance between the flags. While the elevations and higher risk areas delayed the movement between the flags, the distance still felt a bit short, resulting in quite quick matches.
