Investigate crash site

Investigate crash site is the first mission in Ratchet & Clank, set on Veldin. Ratchet watches a ship crash nearby and decides to explore the crash site, which is where he first meets Clank. This mission is the only one in which the player can explore Veldin's Kyzil Plateau, until it is revisited towards the end of the game.

Walkthrough
Ratchet is equipped with two weapons, an OmniWrench 8000 and a Bomb Glove. The former is automatically tied to, which leads to a single swing of the wrench. Hitting it three times leads to the multi-strike, a three-hit combo with some small maneuverability if the stick is used, though it can leave your rear exposed to attacks for a split moment nonetheless. By crouching with and then hitting  Ratchet throws the wrench forwards, called a comet-strike, it automatically returns to him but during this time he cannot move and thus cannot dodge enemy attacks. Lastly he also has a more powerful move called a hyper-strike, activated by jumping with, hitting , which causes Ratchet to slam the Wrench downwards a short distance in front of him.

Unlike the OmniWrench, the aforementioned Bomb Glove is equipped through either the start menu or with quick select. It is a strong mid-ranged bomb weapon, though be aware that using it costs ammunition, which costs bolts, unlike the wrench which is free. Just ahead from where you begin the mission, you can see several horny toads hopping around. They cannot travel to different ground levels, meaning you can easily avoid them by standing on an elevated position, though they are also easily taken out with the wrench.

Dispatch of any toads in the vicinity, while also breaking crates (several of which can be found inside Ratchet's garage) and collecting bolts. Advance further into the area, crossing a bridge and climbing up a platform on the left, then make your way across several gaps. You will now encounter a nanotech crate, which heals one of your hit points. Ahead are two paths, to the left the remains of a ship, and to the right a large amount of crates with several toads—take care of these first, followed by the crates.

Upon entering the left path you will encounter a new enemy: the electroid. These robots will hold a position from which they attempt to electrocute you with a mid-ranged beam of electricity. They will fire at your direction for a couple seconds before powering down, making them vulnerable to a wrench attack. Their down time lasts only a second however, so proceed with caution. Nonetheless the Bomb Glove is still capable of hitting them from afar, as they are stuck in a fixed position when they attack and the Glove's range is greater than theirs.

This is also when ammo crates become available, so make sure to resupply. Ahead are several more electroids which you will have to destroy before you may proceed. There is a circular gateway ahead with two more of the bots inside, that will move away and alarm their comrades, after which they will all take a position and proceed to try and hit you. Destroy them and approach the crash site to finish the mission.
