One thing the review hits right on the spot is the word HUGE. This level is indeed enormous, each room is wide, ceilings are high above, and then there are more rooms, courtyards, and more open spaces, and then some more.
You spawn with all weapons (except for BFG) fully stocked and full armor, so you start fragging right away.
Because of its size, this map only works for populated FFA or TDM matches, you've gotta load as many bots or human players your machine can handle otherwise you'll spend more time looking for people to frag rather than actually fragging 'em.
I'm playing this level on a basic 10 year-old machine (dual core CPU, 8 Gb RAM, an old graphics card) and it runs fine, r_speeds might have been a problem back when it was released (20 years ago) but not today.
One weird issue I did run into was bot play. When I'm play-testing a map, I try bots at least one time on basic skill level (I Can Win) to see how they behave. Normally, bots that are not aggressive on level 1 like Crash, Bitterman, Major and others (as opposed to Xaero, Anarki, Sarge so to speak) mostly run around stockpiling items and weapons and only every now and then engaging in battle.
But on this map, they're all equally aggressive from the beginning even on the lowest skill level. This never happened to me on any other map. I'm playing on good old Q3A v1.32.
