Counter Strike Online Wiki

OICW (Objective Individual Combat Weapon) is an assault rifle equipped with a grenade launcher in Counter-Strike Online obtainable randomly from a Code Box.


The OICW is a next-generation assault rifle that is fed with 30 rounds of 5.56 NATO and fires 20mm grenades. It has high firepower and good rate of fire. It comes with a grenade launcher that can be used against enemies behind cover.

Unlike other grenade launchers, the OICW's grenade launcher fires a low-velocity grenade which bounces off walls like a thrown HE Grenade, exploding exactly three seconds after it's been fired away, instead of exploding upon impact. The grenade launcher's ammunition can't be refilled by any means, and the only way to replenish the grenades is by buying a new rifle altogether.

Tips and tricks[]

  • Use the grenade launcher of this gun to blast enemies who are behind cover.
  • The grenades are so small that enemies may not notice them at all; use this as an advantage.
  • The grenade also works like a Zombie Grenade, to boost the user's jump. This can be done by jumping on the grenade when it explodes. If the timing is right, it will boost the user very high. This trick is very useful in Original and Basic modes to reach certain unreachable areas or finding an alternative route.
  • Do not use this gun for long-range battle, use it in narrow areas instead.
  • In Zombie Mods, never switch to the secondary mode of this gun when escaping from zombies due to the grenade launcher having low knockback and stun power.


  • Damage: Same as AK-47.
  • Rate of fire: Same as most assault rifles.
  • Weight: As light as M4A1.

  • It is stated to use 20mm grenade ammunition in its description, but in texture files, it still uses 40mm grenade ammunition textures.
  • The weapon is based from XM29 OICW, albeit highly modified since it lacks the XM25 grenade launcher the actual weapon has.
  • The OICW's reload animation greatly resembles the G36C's one in Call of Duty: Modern Warfare 3.
  • There's a bug on this weapon where when the player uses the grenade launcher on nearby humans and later gets infected by a zombie, the explosion will kill the humans thus counting them as frags. This bug is very similar to Plasma but instead of infecting it kills. This bug was fixed in later updates.
    • This can also be replicated with an HE Grenade, which is more common in Frag War.
  • Firing the grenades into tilted terrains in point-blank will make it stuck, making a loud noise before exploding.
  • Similar to the Gáe Bolg, it is possible for crafty users to perform a grenade jump with the OICW's secondary fire. Unlike the Gáe Bolg's boost however, the OICW can propel a user much higher with proper timing.
    • For example, this technique can be used to launch a player up to the buttress at the start of Encounter, fired by two other players.

At unknown update of latest ones, OICW is no longer able to perform a high jump. The grenade simply doesn't knockback players in any mode.
