To eliminate other players, your gostek can use a variety of weapons. When respawning, the player can choose one primary and one secondary weapon from a radial menu. As of version 0.8.46.A there are 11 primary weapons, 4 secondary weapons, and explosive grenades.
If you don't hold a weapon, pressing the fire button will make you start throwing punches, and if you go prone while using jet boots (a.k.a. superman), headbutting an enemy at high speeds can deal significant damage. You're never truly unarmed!
The equipped weapon can be changed using the swap weapon key (default key Q) or thrown away using the throw key (what is the default?). The radial menu can be hidden for the duration of the current round (default key: B).
Primary weapons
The primary weapons are the main damage dealers in the game. Each requires a different playstyle and can work better or worse in specific conditions, e.g. Rheinmetall works better at a distance than in close quarters combat. They may also differ in reload style – entire magazine vs. reloading each bullet separately – or in other less obvious stats, like flag push force.
Deagles
A pair of the Desert Eagle semi-automatic pistols.
It has 9 bullets in a magazine and each click makes both guns fire, so you're firing 18 bullets total before you need to reload.
MP5
The Heckler & Koch MP5 is a submachine gun that works well in close to medium combat.
Its magazine contains 30 bullets, but it's best to fire in controlled bursts due to its high spray coefficient.
Steyr AUG
The Steyr AUG is a bullpup assault rifle, a good all-around weapon.
All of its 25 bullets travel far and fast, but that nimbleness comes at a price of a rather long 2.7 second reload time. Steyr AUG used to have 30 bullets per magazine, but got nerfed in v0.8.44 to 25.
Spas-12
The Spas-12 is a semi-automatic shotgun. It is very effective for close quarters combat and is also popular due to its boosting abilities to accelerate speed on your movement, boost flags or boost your teammates.
M79
The M79 is a grenade launcher, which is good for close-mid combat. It kills in one shot and is also good for boosting yourself, teammates or pushing opponents away. The M79 does also deal splash damage if you hit the ground nearby your enemy!
Getting hit by enemy bullets will bink you.
Dragunov
The Dragunov is a sniper rifle, which is good for range combat and as a supportive weapon. It usually kills in 2 or max. 3 bullets. Your accuracy decreases while moving.
Barrett
The Barrett Sniper Rifle kills with just a single shot. You may also kill multiple enemies with the same bullet if the targets line up.
The BulletKickBack is quite high, making the Barrett also useful for self-boosting (e.g. when escaping during backwards superman).
Your crosshair scale indicates your accuracy. Your movement speed decreases your accuracy. Getting hit by enemy bullets will also bink you.
Rheinmetall
The Rheinmetall MG 3 is a german machine gun. The weapon's design is derived from the World War II era MG 42.
Rocket Launcher
The Rocket Launcher, as the name slightly suggests, launches rockets. Their explosions push enemies/flags/pickups away, with splash damage that's big enough to kill through thin walls.
You spawn with all 3 rockets ready to shoot, and each click fires one. Your gostek reloads every rocket individually, so it's possible to interrupt the reloading animation and fire again. Note that, annoyingly, the first click will interrupt reloading without shooting anything – you need to click again to actually shoot.
Its rockets expire after 2 seconds, exploding (and dealing damage) in mid-air; since the projectiles are rather slow, you can see explosions of your own RL if you're fast enough.
While the explosions push flags, the rockets themselves pass through them without moving the flag even one pixel, so don't rely on rockets to make power throws.
Due to its pushback, the Rocket Launcher works good for self-propelling by shooting in the opposite direction.
Minigun
The Minigun is a heavy machinegun, with a large amount of ammo. It's accuracy decreases drastically during movement but is very accurate when you stand still or are in prone/crouch position. It's also very effective for boosting yourself, boosting teammates, boosting flags or pushing enemies away.
Continuously firing the Minigun will cause overheat.
Secondary weapons
Makarov
The Makarov pistol is most useful in combination with one-shot weapons (M79, Barrett) or with the Dragunov.
Knife
The Combat Knife can be thrown, very useful for spawn killing or instant-knife-kill upon re-spawn to prevent enemies from capturing the flag.
Chainsaw
The Chainsaw is perhaps the hardest secondary to use. You will need a good concept of movement to use it to your advantage, but if you do, you can catch your enemies off guard.
RPG
The Rocket-Propelled Grenade launcher has the unique feature of its guided projectile. Hold the fire button (default key: left mouse button) and move the crosshair around to make the projectile follow it.
It has 1 grenade that takes six seconds to reload. The reloading starts the moment you shoot, so it's possible to guide the fired projectile while readying the next one.
Since it can curve around corners, it's a great weapon to get rid of campers or flaggers hidden behind a wall. If the wall is thin enough, the RPG can deal significant damage to unfortunate beings on the other side.
The RPG is a great weapon for rocket jumping, i.e. shooting right next to yourself for a massive push. You're sacrificing a bit of your health (and one bullet that's slow to reload) for a large boost to your own speed, which can aid in escaping with a flag.
Like Rocket Launcher's rockets, the RPG's projectile doesn't push the flag at all. You need to cause an explosion nearby to get it pushed.
Other weapons
Headbutt
Colliding head-first with the enemy
