As much as this map imitates the layout of a real laser tag arena, keep in mind that most of those real arenas suck. Don't be afraid to take this to the next level. First, I'd recommend making the bases a bit more distinguished and the obstacles in the arena a bit more... crazy! An update to the map would be relatively simple and take very little forging skill while yielding a big payoff. I might just have my own try at building one of these arenas.
Original idea but the map brings down the quality substantially. Spend some more time cleaning it up and blocking all exits (including grenade jumping) Other then that good idea.
