FireBall 2

FireBall 2 is an arcade survival game in which you control a fireball, dodge swarms of enemies and set off bombs to destroy them. You can trigger bombs directly or indirectly, or lure enemies into their blast radius. The game supports local co-op for two players, with a second player able to join at any time; the game does not adjust its mechanics or difficulty when they join.

Bombs and upgrades

Boosting lets you move at unlimited use, but forces you to travel at maximum speed. The faster you move, the faster the enemy flood reacts. Destroy enough enemies and their remains form a Nova, which explodes and makes your fireball bigger, faster and tougher. Once your fireball reaches maximum power, each Nova becomes a Supernova. Two Novas can also merge into a black hole that grants temporary invincibility, and Novas can revive dead players.

Waves and scoring

FireBall 2 has two gameplay modes, two difficulty levels and multiple starting waves. Each wave changes the size of the world and the pattern of enemy spawns, while pressure gradually increases as you advance. A combo-based scoring system rewards you for gathering enemies within a single bomb's blast radius, but building larger scores reduces the number of Novas generated. Your approach therefore affects the balance between scoring and survival.

Game modes

Normal mode has smooth, predictable enemies that pursue you constantly. Chaos mode moves at a slower pace: enemies are slower, try to keep you from reaching bombs and also spawn in response to your movements, requiring you to anticipate their actions and take more risks.

Normal difficulty lets you survive minor mistakes more easily. Hardcore difficulty unlocks when you reach Wave 11; it increases the speed of both you and the enemies and doubles enemy damage. Scoring is tracked separately for each combination of gameplay mode and difficulty.

Enemy swarms

The game can display up to 100,000 enemies at once, alongside over a million particles. The background responds to the action, including its movement and explosions.
