Okay so I was playing some nuclear throne today, and thought I'd show you some pictures.
So I took some screenshots and then I fucked them up a couple of times because I'm a total novice, but I'll show you what I've got anyway.

so I took YV for a spin. He is from Venus and starts with a Golden Pistol, which (maybe) has a higher rate of fire, but I'm not sure. His special is when you right click he shoots twice simultaneously, which sounds kinda lame but really isn't. His special doesn't work for melee weapons, as his original character came from a Vlambeer game 'Gun Godz' and it's all about shooting aliens with guns or something... I picked a laser pistol and my first mutation was laser brain so things were good.

it occurred to me it'd be a good idea to screenshot me fighting the Big Bandit, the boss on level 1_3. But I had already killed him so I screenshotted his corpse. sorry

I know I said YV's ability doesnt work with melee weapons, but he can still use them. The hammer is great in the sewer (2_1) because it kills rats in one, and you can hit them around corners. You can see some dead alligators. Double-high-damage-laser is good vs lazy alligators.

So I finally found my car but I forgot the keys.
This is 3_1

If you do level 3_2 right, it can take you to a secret room where you can choose a crown. Each crown has advantages and disadvantages. You can't see any of the crowns because I only saved half my screenshot because I'm retarded. You CAN however see that I am way low on laser ammo. Despite that I chose the CROWN OF GUNS which means more weapons are dropped but you never get ammo drops. This was a really dumb move.

once again my well intentioned attempt to screenshot a boss is hampered by me not doing a good job. I almost immediately ran out of laser and had to take the Big Dog out with a hammer alone. This isn't too bad because all his projectiles can be smacked back into him, and if you're careful you can hit him a few times without stress.

so after the big dog blew up, I went and checked to see what guns were around. There were loads of shit guns (at least for this stage of the game) and the only piece worth looking at was this Double Shotgun. Y.V.s right-click can make this a quadruple shotgun, which is cool. The problem is though this is a cursed box. If I pick up the shotgun, I can never drop it.

The plus side is that it emitts purple smoke. So fukken cool

I totally forgot to take a screenshot of level 4_1. Sorry. The shotgun was a godsend and put many floating laser-shooting crystals to rest. Heading to the next level though, I'm almost out (each shot uses 2 shells) and the levels are only getting more ammo-intensive.
I chose the 'Shotgun Fingers' mutation which makes shells bounce like crazy. The double shotgun produces 8 projectiles I think, and now the likelihood each will collide with an enemy is much better.

I almost immediately ran out of shells, got jumped by yetis, died horribly.
Moral of the story: Don't run out of ammo I guess.
