Same great stuff with new additions
Ok, one of the first things you will notice is that Clanks gone (OMFG!!!!!!) and instead you get two helper bots who will put shields up, crank bolts and help in combat. You can upgrade their weaponry but of course for a price. This is a great new feature to the game that i myself enjoyed.
The maps seem pretty much the same but they are different to the previous games' maps. You have the gladiator battles in the battledome and you have the planets. The planets are deserted wastelands pretty much, usually with scattered ruins. (most likely because it is based in the Shadow Sector) The other games were more based in cities or enemy's bases. Although the new ones are good i liked the city ones aswell. But I would also like to see a ratchet game with war like combat instead of 1 onto 50.
Anyway the new weapons and veicles are cool too. The landstalker is a new edition and is my favorite. There are hoverbikes which are speedy but weak, there is the puma with is an upgraded version of the veicle from the 3rd game and a redone hovership. The weapons are good but you only have 10 but you have a whole bunch of mods you can add to it. Most of the weapons are the same just a little bit different or renamed.
There arent any races like in Going Commando with hoverbikes or space battles. So that is a downside but the gameplay itself is great. and anyone who liked the previous games are sure to like this one.
It seems that this game was a chance for Insomniac to try out some new ideas and it seems like the next game will go back to more of a Up Your Arsenal game with some of the features from deadlocked.
