I wouldn't recommend you go by other's opinions, but instead read the wiki description of each gun, and watch how the gun behaves in battle. Maybe Youtube can help with that. See if it's capable of affecting the enemies you'll be facing the most.

But I'll go on a limb and say don't pick Magnus unless you're a collector. It's the most stupid gun ever designed in this game. I crafted up to Mega Magnus and have the Iron Slug recipe but I won't bother crafting unless I'm really rich. If someday it becomes capable of shotting while walking then it may be worth a try.

Callahan is godly.

Also, that catalyzer looks pretty nice. If they made it so that explosions from charge attacks detonated latent charge attacks on other monsters in the radius, but reduced the total number of charge attacks you could have out at once, I could see it becoming a really useful weapon for crowd control.

How long does the charge field last?

the problem with the catalyzer can be summed up in three points

1. it's time consuming to attach the charged fields to enemies even with its extremely fast charge time. plus the speed at which the bullets go this make its hard to land one accurately (not to mention those enemies that dodge projectiles)

2. in the time it takes to attach charged shots to enemies could cause a problem in that the enemy can still swarm you in that time. even if you were smart and avoid this you would more than likely use the normal gun shots instead of the charges which kinda defies the point imo

3. possibly the biggest issue, there's a very good chance you will be in a group namely PUGs. this leads to the dilemma where all that hard work to attach charges fields to enemies is laid to waste as your teammates cut down the enemy horde swiftly. this causes the charged fields to disappear without detonating (unless you detonate as they are in their death animation like with trents).

Yes, they are fun to use indeed. I can't completely enjoy my Polaris though because of the damage bug (and I have a sinking feeling they won't fix it anytime soon, if at all)...

"If they made it so that explosions from charge attacks detonated latent charge attacks on other monsters in the radius, but reduced the total number of charge attacks you could have out at once, I could see it becoming a really useful weapon for crowd control."

"It already does that."

No, the Youtube demonstration earlier in this thread has one such potential chain-reaction at 1:07. But it doesn't go off.

The secondary target was clearly hit with the initial explosion, as it gets blasted off its feet. But its orbiting charged shot doesn't detonate.

I'll be honest with y'all. The Toxic Catalyzer has completely replaced my Shadowtech Alchemer. First of all, it's a no-ricochet gun which means that it's rather useful on levels where you don't want to hit switches accidentally (*Cough* Ironclaw Munitions Factory *Cough*). It also allows you to kite like crazy while stacking charges on multiple monsters. Then you just shoot normal bullets and watch the fireworks :D. The poison status is also extremely useful in terms of keeping Menders from healing.

I'm not sure about the Pulsar line of guns, I plan to get one soon to test it out. Who knows, maybe it'll be my voltech replacement too.

Hey, they're still 'useful' when wolvers are around. T3 danger room with wolvers and gremlins? Just shoot at wolvers while the others whittle away at the gremlins lol.

Shoot at a wolver, turn around and sword.

I don't know why anyone chooses to engage T3 wolvers with anything but bombs. They're tricky to engage in melee, and using guns around them is hazardous. But they LEAP into your bomb radius, no matter where you are. You can target indiscriminately and you'll still nail half the wolvers on the map.

I think the pulsar is the best for a single gunner. It has more range than the drivers. And the antigua line isn't very good. Split damage is bad.

My 4* Gigawatt Pulsar deals more damage than my hail driver level 10. My GW Pulsar also stuns which, minus it's attack speed; is better than the storm driver.

Go pulsar

I am not planning to take on Royal Jelly with two 5* weapons. I do plan to eventually get two 5* weapons, though.

As for the Roarmulous Twins, from what I can tell the only aspect where your weapon matters much is killing the minions, as most of the fight is oriented around having them blow each other up, making weaponry less important than a good armor/shield set for them.

I would probably be going after RJ using the 4star version of either the poison catalyzer or the poison striker line.

I just tried the catalyzer. I can't recommend it as a primary gun in it's base form. The bullets are way too slow.

I got suspicious when an Ironclaw Scorcher outran my bullets. I don't mean that sidestep thing they do. It was retreating on low health. It. Outran. My. Bullets. (more like outwalked at the rate it was moving.) I tried to shoot straight and run in the direction of my bullets. Turns out you run faster than catalyzer bullets. I passed my own bullets about 2/3's of the way though their range, even given the head start that they have when you pause to shoot them. It's hard to hit anything that moves with that gun. You can use it on slimes, turrets, lumbers, and undead, but that's it.

Maybe the upgrades are better, but based on first impressions, do not obtain the catalyzer.

@Zanoni

I thought you were lying or being stupid talking about the catalyzer bullets, but I got me a new one (and a CTR:Low UV on the 3* upgrade!) and it turns out you were right: Catalyzer (2*)'s bullets are REALLY slow, and you CAN run past them. After I upgraded it to 3*, I found myself able to run behind and 'renew' the shot as it fizzled out.

Not sure about the Neutralizer yet, but as far as the Biohazard goes, I run behind the bullets. I think they move the same speed as running.
