If you find the "Toy Gun" weapon, keep it. It requires 300,000 Gil to upgrade it. The first upgrade makes it a Silver Toy Gun, and the next upgrade makes it a Gold Toy Gun. The final upgrade costs 200,000 Gil and creates the Ultima Weapon.Easy Gil and experience
In Kalm, with the "Help the WRO" mission goal, run around the center tower killing Deepground soldiers. As long as you stay away from the gate with the white boxes and mana springs, you can kill an unlimited number of soldiers gaining as much experience as desired. Soldiers will randomly drop ammunition and potions to keep you going indefinitely. After the desirable amount of experience has been obtained, continue with mission up until the snipers. Kill two and allow the last sniper to kill you. With the restart, you will be able to use the experience to level up or gain a lot of Gil. Then, do it one more time for more Gil or experience, but make sure not to die the second time through and to defeat the helicopter Boss.
You can take advantage of the checkpoints within chapters. If you die at the end of a segment, just before the next checkpoint, you can use the experience for Gil or leveling. This trick can be used by looking at the save points on a completed game or while following a more detailed walkthrough. For most, the best strategy will be to use the first experience to level which will then make re-playing the level even easier. At the end of the level, you may lose some stats for dying, time, and damage, but you can then use the final experience for a large amount of Gil. You can only die once per checkpoint for this to work and manual restarts will not do the same thing.Help from bugs in Chapter 6
After you get to where all the DG soldiers are, you can shoot over where the insects are. Use the Hydra Gun to shoot the one in front. They should get mad and think that the DG soldiers did it. While they are attacking the soldiers you can rest. After they are done you can kill them.Cloud reference
In the third mission (the one going to Edge City), you will have to save a boy. After you chase him out of the building, the camera will pan away from the building. You will see a small icon of Cloud Strife on a dirty cloth hanging from that building.Fenrir reference
The Gummi Ship special model "Fenrir" is a motorbike with Cloud on it. This is the same motorbike he uses in Final Fantasy 7: Advent Children. Before he leads the raid on the force "Deep Ground", he says "Lets go..... Fenrir".Short Circuit reference
On the Shera, when talking to Reeve Tuesti, he mentions that he managed to salvage something from the ruined WRO headquarters. A Cait Sith will walk up and say, "Number 5, is alive", which is a direct quote from the robot Johnny-Five in the 1986 movie Short Circuit.
