Usage and Buying:

 * Spec Ops is the best option for Survival as Invis allows you and your supports untargetable for a long time.
 * Invis can save you if used in a dangerous situation like Missile Shooters + Plasma Shooters Combo (often a run killer combo).
 * Invis is OP in PvP despite experienced player being able to see invisible enemies.
 * When using Invis in PvP, almost every homing attack cannot home into you. This ability hard counters homing attacks HMA, HML (literally everyone's weakness), and EBL (another weakness to everyone).
 * It's difficult to see invisible players without negative effects.

Combos:

 * Invis + Super Force Field is a wonderful combo in Defence and Assault as the enemies target mostly (always if Cs MK-2 user is the only visible player). SFF has infinite armor and only lasts 3 less seconds compared to Invis.

Counters:

 * Spec Ops is difficult to counter due to high speed and Invisibility.
 * Invisible Spec Ops and supports appears to be darker and more transparent than without the ability.
 * Negative effects can "reveal" invisible enemies although supports and homing attacks still do not attack them. The negative effects are still visible when applied on an invisible enemy.
 * The best way to "reveal" invisible enemies is Napalm. The burn lasts for 5 seconds and "reveal" players.
