Absolute Annihilation mod

Absolute Annihilation is a massive total conversion project for Cavedog Entertainment's 1997 RTS title, Total Annihilation. The mod's aim is to completely update the gameplay, while keeping it consistent with what was developed in the original game.

From the readme:

Absolute Annihilation is the product of hundreds of hours of exhaustive testing and
very hard work. It has, in my opinion and that of many others, turned out extremely
well. This mod doesn't have as many units as packs such as TAUIP or UTASP, but I
think that mine is of a higher quality overall. I played with those mods for over a
year, and in that time I can still remember a lot of units which were not merely
unbalanced, but often times either completely game-dominating or completely useless.
The most satisfying, long-lasting mod experience I've ever had is with Uberhack by
Brave Sir Robin. The key to Uberhack was that the game was added to, without taking
anything away from the original game in the process. This is what I hope to
accomplish with AA, but on a larger scale. It's like what the game WOULD be if units
were still being released weekly from Cavedog.

I've added about 175 units in all. AA is, first and foremost, a mod about balance,
not about ridiculous numbers of units. Shipyards, aircraft plants and the like have
only got two menus worth of units. The Core K-Bot Lab doesn't have even a single
new one, and the arm version has only one extra! This is because I felt that what
was already in place didn't need anything else. This IS Total Annihilation we're
talking about - the game with more stock units than any other RTS to date!

My goal with AA is to make it so that for every form of attack or defense, there
is a countermeasure available. There are no defenses too strong, and no attack too
potent to find a way to beat it.

Hovercraft are now worth building, so give them a try. Scout hover weapons have
been tweaked to give a sort of "Flash-on-water" feel to them, and there are now
heavy hovercraft available to each side which are comparable to a destroyer in
firepower. In addition, there are also radar and radar jamming hovers available,
allowing land stealth tactics to be adapted to water battles.

If you've been watching the "unit IDs used" bit steadily decreasing, it's not a
typo. I've actually been removing units - but only ones which I felt were beyond
salvaging. These removed units have had their roles given to lesser units which
you probably didn't regularly build before.

Also, I'd like to mention that many units, including some Cavedog ones, have been
seriously altered and do completely different things, and that 9 out of 10 units have
been changed in some way from how they were origninally designed. It'll take a while
to learn all these differences, I know, but in the end it's worth it. The point is,
you should build every unit at least once, if only just to see what it does. Many
units that were largely useless or not worth building are now very important. For
example, the EMP and Neutron launchers now fire medium-range cruise missiles which
are extremely effective for destroying rushes of small units or doing that last bit
of damage necessary to take down a retreating 'mech.

Next, I've changed the movement abilities of construction units around a bit.
Construction vehicles' turning speed has been reduced slightly, while kbots have
been given a slight boost to their top speed and building range. While
vehicles are significantly better builders for large projects such as RFLRPCs,
kbots are by far superior in guarding construction facilities and boosting their
production rate. You can fit four construction kbots in the same space as one
vehicle would normally occupy.

All of the units I've included can be found at at least one of the following:
