Gaming Consoles & PCs Best Co-Op Games on OG Xbox by Eric Qualls Writer Former Lifewire writer Eric Qualls has been covering the Xbox line of consoles and Xbox games since August 2004. our editorial process Twitter LinkedIn Eric Qualls Updated on December 12, 2019 Consoles & PCs Xbox Buyer's Guide Tweet Share Email Here are our picks for the ten best co-op games on the first Xbox. The descriptions tell whether they are online or offline or both. Xbox Live service was turned off for original Xbox games several years ago, so the online portions of these games no longer work. Offline play works just fine, of course. 01 of 10 Halo and Halo 2 Playing through Halo 1 and 2 with a friend is the absolute best way to experience the game. It gives you more options and more strategy and it is generally just a heck of a lot of fun. “Accidentally” running over your friend with a Warthog or killing each other until the bodies are stacked ten high are added bonuses. Co-op is offline. 02 of 10 TimeSplitters 2 and Future Perfect Just like Halo, the TimeSplitters games are even better when you play with a friend. There are all sorts of fun hidden references and other goodies and it is a goofy lighthearted experience that is at its best when you play with a buddy. Co-op is offline. 03 of 10 Stubbs the Zombie For zombie fans Stubbs the Zombie is a dream come true because you and a buddy can take control of zombies and create your own army of the undead. Eating brains and infecting humans is a hilariously fun experience that is best shared with friends. Co-op is offline. 04 of 10 X-Men Legends I and II Playing through X-Men Legends I and II with a friend gives you a whole lot more strategy and creates a much deeper and more entertaining experience. Co-op is 2-4 players offline in Legends I and 2-4 players both off and online in X-Men Legends II. 05 of 10 Mortal Kombat: Shaolin Monks Shaolin Monks takes all of the cool stuff in Mortal Kombat – the blood and fatalities and cool characters and strips away the bad stuff (like the cruddy fighting engine). What you are left with is a solid beat-em-up that gets even better when you can work together with a friend. New moves open up when two people play and it is impossible to beat it 100% without playing some co-op. Co-op is offline. 06 of 10 Splinter Cell: Chaos Theory Co-op in Chaos Theory takes place in unique levels that were designed with two players in mind so it is a completely new experience from the single player game. You have a bunch of new moves to use and playing with two people opens up all sorts of strategy that the single player game lacks. Co-op is available in splitscreen as well as on Xbox Live and system link. 07 of 10 Doom 3 Doom 3 is a scary game, but you can be a bit more confident when you know your friend has your back. It makes the game quite a bit easier when you have two people blasting demons, but it is considerably more fun. Co-op is available over Xbox Live and system link only. 08 of 10 Lego Star Wars Lego Star Wars is cute and a tad on the easy side, but it is still Star Wars darn it. You have dozens of characters to choose from and it is a lot of fun to play through with a friend hacking up enemies with your lightsaber. Very fun for Star Wars fans. Co-op is offline. 09 of 10 Ghost Recon 2 and Summit Strike Ghost Recon relies heavily on communication and teamwork, so it is no surprise really that co-op works so amazingly well. You can count on your friends to play a lot smarter than the AI which introduces new layers of strategy and depth. Co-op is available in split-screen and Xbox Live. 10 of 10 Serious Sam II Serious Sam II is a simple, straightforward shooter that doesn’t really add anything new to the genre but is undeniably fun. Even better is that you can take it online and play co-op with up to three other people and the best part is that the game ramps up the number of enemies in the level depending on how many people are playing. Genius! Co-op is available on Xbox Live.
