近期更新
增强部分角色能力,降低部分场景难度,强化部分偏弱的 Boss,并修复某个白色布料贴图不显示的问题。本版进一步调整希娜基地关趴下动作的裙褶与腿部比例,更新说明和致谢。
主要特色
- 六名角色:比尔、兰斯二段跳,RD008、RC011 短暂悬停,狼人高跳;希娜落地前最多三次八方向突进,不能连续同向,并带踩踏伤害。
- 双武器切换:随身携带两把枪,按 SELECT 切换;交叉前进的双火球、强化散弹与加粗激光,带来不同打法。
- 更多动作:加入飞踢、踩踏、滑铲,跳跃高低也能控制。特殊动作主要用于横版关卡。
- 双人合作:并肩闯关,同时碰到同一道具,两人都能获得效果。
- 全新演出:六人立绘、组队开场、队伍合照与角色通讯。
- 原曲重混:水下八关及基地头目战重新编曲,保留熟悉旋律,加入新的伴奏变化;经典八关音乐不变。
- 自由设置:可选起始关卡、生命、接关次数、初始武器与无敌模式,并支持六种语言。



基本操作
方向键移动/瞄准,A 跳跃,B 射击,SELECT 切换武器,START 暂停。
横版关卡中,按住 A 的时间控制跳跃高低;地面依次输入下 → 前 → A 滑铲。其他角色空中下+A 踩踏、斜下+A 飞踢;希娜空中再次按方向+A 突进,每次需松开再按 A,接近地面时不能发动。不按 A、只按反方向可取消突进并下落。
比尔、兰斯使用 S,机械人使用 M,狼人使用 L,希娜使用 F 时,默认带有原本的 R 效果;R 道具仍正常生效。默认接关 255 次,全灭后按 START 先选人,再回到当前场景的死亡位置;按 SELECT 结束游戏。普通过关对话后也能重新选人。
Boss 强化只作用于水下篇:第五关双雪山 Boss、第六关三巨神兵、第七关接力战与炮台,最终关则加入瞄准连射、激光扫射和地面冲击波。

Recent updates
Recent updates enhance some character abilities, ease selected scenes, strengthen underpowered bosses and fix a missing white-fabric sprite detail. This release further refines Sheena’s base-stage crouching sprite, skirt pleats and leg proportions, with an updated guide and credits.
Highlights
- Six characters: Bill and Lance double-jump, RD008 and RC011 briefly hover, and Werewolf jumps high. Sheena can air-dash up to three times in eight directions with stomp damage; consecutive dashes must change direction.
- Two weapons: Carry two guns and switch with SELECT. Try crossing twin fireballs, an upgraded spread gun and a thicker laser.
- More moves: Flying kicks, stomps, slides and variable-height jumps add options to side-scrolling combat.
- Co-op: Fight together. Touch the same pickup simultaneously and both players receive its effect.
- New presentation: Character portraits, a team opening, a group picture and radio scenes.
- Original-theme remixes: Underwater stages and base boss battles keep familiar melodies with new accompaniment. Classic Eight Stages music stays unchanged.
- Your choice: Set starting stage, lives, continues, starting weapon and optional invincibility. Six languages are available.



Controls
Directional pad: move / aim. A: jump. B: fire. SELECT: switch weapons. START: pause.
In side-scrolling stages, hold A longer to jump higher; input down → forward → A on the ground to slide. Other characters use down + A in midair to stomp and diagonal down + A to kick. For Sheena, press a direction + A again in midair to dash, releasing A between dashes. Dashes cannot start near the ground; press the opposite direction without A to cancel into a fall.
Matching weapons automatically gain the normal R effect: S for Bill/Lance, M for the robots, L for Werewolf and F for Sheena. R pickups still work. Continues default to 255: after GAME OVER, START lets you choose a character before returning to the death position in the current scene; SELECT ends the game. Ordinary stage-clear dialogue also allows character reselection.
Boss upgrades apply only to Underwater: twin snow bosses in Stage 5, three giants in Stage 6, a boss relay with active cannons in Stage 7, and aimed bursts, a sweeping laser and ground shockwaves in the finale.
Playing
Open Contra UnderWater.nes in Mesen. After updating, reopen the game rather than loading a save state from an older release.
