What achievements can I get without the dlc?

My friend just got the rocket launcher achievement. What other achievements can we get without the dlc?

Also, what is resistor? I don’t have that in my perk list.

Ok so on further inspection it would seem there are only 2 achievements you cam get without the DLC at the moment, these are;

One Man Army - In matchmaking, got four consecutive kills with the Rocket Launcher without dying.

Pitchin’ a Tent - In matchmaking, effectively camped one location without dying for a full 60 seconds.

Every other achievement requires some asset of the DLC (such as new maps/mode, tactical package and support upgrades).

This is how it stands at the moment, until everyone gets Ricochet and the new armour mods that is.

Any Achievements that do not say “In Bullseye DLC matchmaking.”

In two weeks when Ricochet matchmaking is open to everyone, you’ll be able to get the Ricochet Achievements as well (assuming that matchmaking will have non-DLC Ricochet maps).

Right now, the only Achievements that are open to non-DLC owners are the ones that just say “in Matchmaking.”

So what is ‘resistor’?

> So what is ‘resistor’?

Resistor is a third new armor mod that is only available to owners of the Champion’s Bundle DLC right now. It will be released to everyone eventually, but we don’t know when. (Some claim that said it would be available in two weeks, but 343i never said this.)

So out of all of the Halo 4 DLC (Crimson, Majestic, Castle and Champions) the only achievements that you can get without buying any DLC are “One Man Army” and “Pitchin’ a Tent”?

I have heard people are able to get certain DLC achievements in Forge.
