DOOM - Oct '93 Press Release Beta (Demo 2)
If you're wondering why this and Demo 3 are in 'the wrong order', it's NOT because of where each map ended up in the retail product. It's because this map is unwinnable due to the engine behaviour being incomplete; certain vital areas are inaccessible.
Anyway, you'll probably recognise this as E3M5, Unholy Cathedral, but with a few differences.
Also, the behaviour of two power-ups is radically different. First is the Light-Amp Visor; it uses a pseudo-nightvision style green filter in addition to the standard 'allbrite' change (although it's considerably darker than the 255 lighting used by the finished equivalent). It also lasts the entire level, or so it seems here.
Next, Partial Invisibility. Uses the same 'inverse greyscale' colormap as Invulnerability does in V0.99 onward, but with absolutely no benefit whatsoever; enemies seem to retain their ability to hurl projectiles with flawless accuracy.
