Combined Operations Lite – Arma 2: Operation Arrowhead

Combined Operations Lite

Note: Combined Operations Lite is also referred as CO Lite or CO:L.

Pretext

⚠

IMPORTANT

This is an unofficial guide and is not done by Bohemia Interactive. CO Lite is still experimental as more feedback from people testing with the various distributions is needed.

What is it

Combined Operations (A2:CO) is the combination of Operation Arrowhead (A2:OA) and ArmA 2 (A2). It extends it with additional content like new worlds (Chernarus and Utes) and various factions and their assets (USMC, Russian Armed Forces, Chernarussian Defence Forces, Chernarussian Movement of the Red Star, National Party).

CO Lite is the combination of OA with ArmA 2 Free (A2:F). It is called Lite as ArmA 2 Free has lower quality textures and sound files.

⚠

NOTE: CO Lite allows A2:OA only owners to join A2:CO servers and therefore it unifies the multiplayer scene.

Even for CO Full owners it might be worth considering to use. See the next section.

Pros and cons

Pros

• More FPS: up 5-15% for both average maximum and average minimum (see PvPscene Benchmark Suite)
• Less texture switching

Both due to the low(er) quality textures for the A2 content.

• Faster loading times:

Due to smaller pbo files.

• Ability to play on A2:CO servers

For people that only own A2:OA.

Cons

• Low quality textures
• Lower quality sounds (though it seems hard to hear a difference)
• A2:F v1.11 does not contain the addon/PBO fixes of standard A2 v1.11

Get CO Full

If you want to upgrade your CO Lite setup to CO Full your best option is to buy ArmA 2 at Sprocket (the online store from the developer itself).

Or buy Combined Operation itself and make your Operation Arrowhead copy a gift to a friend to convert more people to the series. :)

You can also buy ArmA 2 at these alternatives.
