Halo 5: Guardians launched as what was arguably the weakest co-op experience for the series. Despite supporting four player co-op in the campaign, the game lacked local couch co-op for the very first time in any Halo game on Microsoft's console. Combined with the missing Firefight or Spartan Ops co-op mode, players were very limited in the time they could spend with their friends in a non-competitive setting.

The fans asked for it, and it's nearly here. The co-op friendly Warzone Firefight will be added to Halo 5: Guardians and available for all to play very soon.

One of the biggest features of the latest Halo title, Halo 5: Guardians, is the team vs team Warzone. This new multiplayer mode pits two teams of 12 against one another to capture strategic points and score points in a very "DOTA-esque" fashion. Currently, this is a strictly PvP affair, but some of our readers have alerted us to 343 potentially being interested in opening it up to PvE.

The PlayStation Plus subscription model has been a boon for co-op fans in 2012 with plenty of titles being made free as part of the package.  The latest is Anomaly Warzone Earth, a RTS/Tower Defence game that has an exclusive local 2 player co-op mode only available on Sony's console.

Anomaly: Warzone Earth is described as a "tower offense" game. It has been a success on many platforms, first on PC and Mac, then for iOS devices, Android, and finally on Xbox Live Arcade last spring. One thing was missing from the package, though: co-op. The Playstation Network release fixes this oversight with the inclusion of a co-op mode for two local players. So how does the "tower offense" work exactly, anyway, and does the co-op make the experience better, or worse?

Anomaly: Warzone Earth has finally arrived on PSN, but why should we care?  Because it has two exclusive co-op campaigns that can only be found on the Sony behemoth.  The launch trailer is out and contains war, zones, but ironically very few anomalies.

Anomaly: Warzone Earth has been dubbed a "Tower Offense" game. Players form an assault squad and try to defeat alien defense towers. Simple enough. The squad is not controlled directly, rather a player chooses unit paths on the battlefield. In the PC, Mac, and XBLA versions, you could control a commander who would help advancing units by distributing power-ups. Alas, these were all single player affairs.
