Crysis carrier boss guide: TAC Cannon locks and alien warship targets
Quick answers for the original Crysis finale, including why the TAC Cannon will not lock onto every target.
Edition covered
The original 2007 Crysis PC campaign and its four-mode Nanosuit. Crytek publisher imagery is from the original Steam listing. Crysis Remastered, Warhead and later games have different content or controls and are excluded.
Follow the carrier objectives before the final deck fight
Reckoning moves through carrier tasks before the largest alien encounter. Collect the equipment the story directs you to obtain and return to the active objective. The TAC Cannon is a finale tool with specific target conditions, not a replacement for ordinary weapons throughout the mission.
| Stage | Target | Required approach |
|---|---|---|
| Deck exosuit | Large alien on the carrier deck | Use conventional heavy firepower |
| Warship defenses | Four gun turrets | Destroy them with conventional weapons |
| First arm or wing | Shielded warship component | Wait for Helena to lower the shield, then obtain a TAC lock |
| Second arm or wing | Remaining shielded component | Repeat the shield-and-TAC sequence |
| Underside hatch | Closed central opening | Use rockets to open it, then lock the TAC Cannon onto the exposed interior |
| Extraction | Escape route to the VTOL | Move promptly after the final hit |
Use conventional weapons on conventional targets
The early heavy alien encounter and defensive components require suitable normal firepower. Keep moving around cover and replenish ammunition where available. Firing the TAC Cannon at an unsupported target will not force the scripted sequence to advance.
| Symptom | Check | Next action |
|---|---|---|
| No lock indicator | Is this the designated component? | Aim at the prompted target |
| Target still protected | Has the shield stage changed? | Wait for the support dialogue and objective |
| Previous component remains | Was the prior attack completed? | Finish the current stage first |
| Objective changes to escape | Is the fight sequence finished? | Stop aiming and reach extraction |
Wait for the shield and target instructions
During the alien warship fight, the supporting characters communicate when a designated target can be attacked. Aim at the required component and allow the lock to complete. If it refuses, check whether the prior target or shield stage has actually finished.
Leave when the final escape objective appears
After the required warship sequence, move toward the extraction prompt instead of remaining beside the collapsing fight. Keep a save before the deck confrontation. If a lock fails, use the stage table to check the current target and wait for Helena’s shield instructions before trying again.
The TAC Cannon locks onto designated warship targets after the required shield or hatch stage; use conventional weapons for the deck exosuit and four turrets.
