Ratchet Deadlocked is perhaps the greatest shooter every to be realesed on the PlayStation 2!
There are also alpha mods in the game. Alpha mods can increase your weapons impact, area, speed, and much more. The mods are not the only great part of this game though. In addition to the mods there are ways you can upgrade your weapons. When you upgrade your weapon it becomes more powerful. Before you beat the game you can upgrade each of your weapons up to v10. But when you beat the game something will appear in the Vox Vendor that are called megas. Megas can be obtained if you get your weapons up to v10, and if you get enough bolts ($) to buy them. There is a mega for each weapon and when you get the mega you can upgrade the weapon that you bought it for up to v99. In addition to all that there is different armors, wrench upgrades, (melee weapon) bot upgrades, (helpers on the battlefield) arena challenges, the bolt multiplier, secondary missions, 5 bosses, and lots extra goodies. As you can tell this game is huge and a lot of fun. I highly recommend you go out and buy it.
