What equipment are made available to the players by Gantz? Before a mission starts, the players are typically issued get a gun, a rifle, and a black suit, but later on, you see that some of the player wielding a blade. What other weapons, suits, or vehicles are made available to the players (including the ones unlocked by the 100-point menu)?
As you said, at the beginning, the players find the following:


Gantz Suit

Provides the wearer with incredible strength, speed, endurance, and the ability to jump very high, as well as land without problems
Provides the hunter with an almost impenetrable protection to his/her body, including the head

Controller

Used to track the targets, displaying the targets as well as fellow team mates on its screen

X-Gun

Fires until it hits something, then explodes inside the target after a delay

X-Shotgun

Meant for longer range, has higher accuracy, and a sniper scope

Y-Gun

Has the same lock-on capabilities of the X-Gun, but rather than fire out an explosive payload, it instead launches three "laser anchors" connected by ropes



Other non-100-point items are:


Gantz Sword

Seen scattered amongst the floor in the same room as the Monobikes
Has an incredibly sharp blade that extends from the hilt without loss of durability

Gantz Bike

Made its first appearance before the start of the Dinosaur mission
A type of monowheel, with a seat for a driver and a rider, its own radar, and the ability to go into stealth mode



100-point items are:


Z-Gun (sometimes referred to by fans as H-Gun)

Applies severe gravitational force in a circular area and forces everything within range of the shot to slam into the ground or be flattened

Hard suit

Is far stronger and much more resistant than the normal Gantz suit
Has a built in X-ray scanner, a beam weapon that fires out of its palms, and sharp swords protruding out from the back of the elbows
