Combat Guardian: Under Attack
About Combat Guardian: Under Attack
Combat Guardian: Under Attack is built around a single number that never changes - fifty states, cleared one at a time, with a boss fight breaking up every tenth one. WASD or the arrow keys move while the mouse handles aiming, and the left click fires, but the F key special attack is what actually decides the boss fights, since regular fire alone is too slow to break their health bars before they close the distance. Early states are mostly about clearing rooms of regular enemies before the exit unlocks, and the difficulty curve is gradual enough that a mid-run boss rarely feels like a spike - it's the states right after one, when enemy density jumps back up, that tend to catch players off guard instead.
How to Play
- Move with WASD or the arrow keys.
- Aim with the mouse and left-click to shoot.
- Press F to unleash the special attack, especially useful in boss fights.
- Clear every enemy in a state to unlock the next - a boss waits every tenth state.
Combat Guardian: Under Attack FAQ
What does the F key special attack actually do in Combat Guardian: Under Attack?
It fires a stronger attack than the regular left-click shot, and it's built around boss fights specifically - trying to whittle a boss down with normal fire alone takes long enough that they usually close the gap and punish you before the bar drops far.
Do the states get harder evenly, or in jumps?
In jumps tied to the boss fights - the state right after a boss tends to throw more enemies at once than the state before it, so the difficulty spike lands right after a win rather than building up gradually toward the next boss.
