Found this on StackExchange, props to Isuka:
Of note is that this only applies to the final mission, you can happily upgrade throughout the game, just make sure your squad going into the final mission is downgraded. (Tip: Psionics/Dominate is AWESOME).

Only Tier 0 items:
- Assault Rifle, Pistol, Shotgun, Cannon, Sniper Rifle, Sword, Gremlin Mark I, Psi Amp, Grenade Launcher
- Nanofiber Vest
- Medikit
- Frag Grenade
- Flashbang
- Smoke Grenade
- PCS Upgrades
- Weapon Mods

Exceptionally, the following upgrades are allowed: (since you can't downgrade)
- Alien/Plasma Grenade (Permanent upgrade to Frag Grenade)
- Nano Medikit (Permanent upgrade to Medikit)
- Smoke Bomb (Permanent upgrade to Smoke Grenade)

Forbidden Items include (not comprehensive - ANYTHING not in the list above may be bad):
- Skulljack
- Battle Scanner, Mindshield, Mimic Beacon
- ANY Special Ammo (Talon, Venom, Dragon, AP, etc.)
- ANY Special Armor (EXO Suit, Warden armor etc.)
- ANY Special Grenade (Gas, EMP, Acid Grenade/Bomb, etc.)
- ANY better weapon (Advanced Grenade Launcher, Arc Blade, etc.)

In essence, the game checks the inventories of all soldiers and makes sure that you only have Tier 0 items, with the exception of the three permanent upgrades (Alien Grenade, NanoMedikit, Smoke Bomb) and any drops you got throughout the mission.

In addition to the excellent solutions by labtoy and Lt Davo I'd like to add some more tips to beat the final mission itself.

First of all, Rookie difficulty is key. Enemies are far more likely to miss their shots at you, and it feels as if your shots hit them way easier especially at low hit percentages. This will also avoid save scumming, because you simply won't need it.
Make sure to give all of your weapons an upgrade, such as the hair trigger or laser sight. Extended clips or auto-loaders are not recommended, as you will have more than enough time to reload.

Once you start the battle, move slowly. Only use the first action to move (the fields that are highlighted in blue, not yellow) and put your unit on overwatch at the end of the turn. As the mission is not timed, you can definitely take your time here.

Even though all your soldiers will have the standard gear, your Commander's Avatar will have a powerful gun, and even more important, PSI attacks. Make sure to use his gun, the lance, and the mind control on enemies that can't be killed by other soldiers, or to simply keep them occupied for one more turn so that the other soldiers can kill them later. In addition, if you gave your grenadiers the "rain of bullets" ability, use it frequently as well, as this guarantees a hit with a decent amount of damage dealt.

By moving forward slowly, you should only encounter one enemy group at a time. As soon as you discover the group, they will become alerted and disperse. Here's the important part: Directly following the discovery, use your Commander's Avatar to hit the group of enemies with his dimensional rift ability. It's radius is so wide that you should be able to hit the entire group of enemies most of the time, either killing them right away or significantly weakening them. This will make it very easy for your remaining soldiers to kill the weakened enemies off one by one. As an example - you will encounter a group of six or seven MECs early on; I was able to kill all of them but one with a single dimensional rift attack.

As soon as the group of enemies is killed, do not continue moving forward. Have all your soldiers reload your weapons and overwatch, until your dimensional rift attack is available again, which should take five turns (you'll have any other ability such as "rain of bullets" available again as well). Once that is done, proceed forward.

At later waves, moving forward after encountering a group of enemies might trigger a second group, so better stay put and keep your soldiers in cover until all enemies are dealt with.

As soon as you enter the final stage, it's all about killing the three avatars, you can almost ignore the other enemies. New enemies will spawn constantly, so you won't be able to keep up, anyway. Keep in mind though that the Codex can disable your weapons, forcing you to not only move your soldiers but also to reload, potentially wasting an entire turn, so you might want to take them out if the opportunity exists.
Again, the Commander Avatar's abilities are the best weapons here, so use them as much as possible.

If you did not train any rookies to become PSI operatives, do not worry. It will help you beat the mission just as Lt Davo mentions, but the mission is also very much doable with the Commander's Avatar being the only one with PSI abilities.

Go get 'em, Commander!
