Double Jump
This foundational move adds verticality to basic jumps, essential for clearing wide gaps or scaling platforms.

Step 1
Run and press jump to launch into the air with full momentum.
Step 2
While airborne, press jump again mid-flight to trigger the second leap, gaining extra upward thrust.
Step 3
Aim slightly upward during the second jump to maximize height, then chain into a glide or dash.
Step 4
Practice timing on multi-tiered platforms; combine with slides for evading ground fire while ascending.
Wall Run
Wall Run lets Jack defy gravity by sticking to vertical surfaces, building speed for advanced maneuvers.

Step 1
Sprint toward a wall at full speed, holding forward.
Step 2
Jump into the wall to latch on; Jack auto-runs upward or sideways based on angle.
Step 3
Hold the direction key to extend the run; release or jump off early to redirect momentum.
Step 4
Transition to Double Jump at the run’s end for wall-to-wall chains, ideal for narrow corridors.
Tail-Copter
Jack’s tail spins like a propeller, offering brief aerial control after jumps for precise landings.

Step 1
Jump off a surface or ledge to gain initial height.
Step 2
Press the Tail-Copter input to activate rapid tail spin, slowing descent.
Step 3
Steer left or right while hovering; it lasts 3-5 seconds based on upgrades.
Step 4
Cancel early into Tail-Hook or Double Jump; use over hazards to scout enemy positions.
Tail-Hook
The tail extends as a versatile hook, yanking Jack to out-of-reach spots or pulling objects.

Step 1
Spot a grapple point (glowing ledge or ring) within range.
Step 2
Aim with mouse and press hook button; tail latches instantly.
Step 3
Hold to swing or reel in; release mid-pull for momentum boosts.
Step 4
Chain with Wall Run on arrival; breaks certain barriers as a bonus melee tool.
Warp Pipe
Warp Pipe accesses hidden paths through sewer systems, shortcuts, or enemy flanks.

Enter green-rimmed pipes scattered in levels, often behind destructible walls. Hold the interact key near one to dive in, emerging at linked exits. Pairs perfectly with Monkey Vault to reach high entries. Use sparingly in combat to reposition quickly without losing speed.
Monkey Vault
This parkour staple vaults low cover fast, keeping Jack’s flow uninterrupted during pursuits.

Step 1
Approach a low obstacle (crates, railings) at sprint speed.
Step 2
Jump toward it, placing hands on top without slowing.
Step 3
Pull body over with arm push, tucking knees to clear fully.
Step 4
Land running to maintain momentum; upgrade extends vault distance for gaps.
Practice Locations
Test these moves in Mouseburg’s alleys and factories, where pipes cluster near grapple walls and low vaults line rooftops for combo chains.
Optimizing combos for tough fights
Link abilities ruthlessly: Wall Run to height, Tail-Hook across, Double Jump redirect, Tail-Copter adjust, Monkey Vault obstacles, Warp Pipe escape. Prioritize upgrades for boss arenas with vertical puzzles.
These abilities elevate simple shooting into dynamic detective work, rewarding precise playstyles over button-mashing.
