What is GrimWar?
GrimWar is an online arena game where you play as a wizard trying to be the last one standing. You move around a shrinking arena, dodge spells, and try to knock other players into the lava. Think of it like a top-down Smash Bros with magic — the lower your health, the further you fly when you get hit.
Games are peer-to-peer, so there's no sign-up or server to deal with. One person hosts, everyone else joins with a code, and you're playing within seconds.
Controls
- WASD to move
- Left click to cast your spell

Two Ways to Play
Roguelike Mode
Everyone starts with the same basic fireball. After each round, the losers pick a random power-up card that sticks with them for the rest of the game. Some cards are straightforward — more damage, faster cooldowns, extra projectiles. Others are weird and risky. Death Wish triples your damage but drops your health to 30. Blood Magic lets you spam spells but costs health every time you cast. Ghostfire makes your fireballs invisible.
Before each round, players vote on a modifier that changes the rules — things like low gravity, double speed, or an arena that shrinks immediately. There are also random hazards during rounds: fire geysers, slippery ice patches, wind that shoves everyone sideways, and small meteors raining down.
Arena Mode
You earn gold each round and spend it in a shop between fights. There are over a dozen spells spread across four categories, plus blink variants that change how your teleport works. You can rush through enemies, swap positions with someone, or just get a longer-range blink. Each spell can be upgraded through three tiers.
The strategy is in how you spend your gold. Do you grab a cheap utility spell early, or save up for a big power spell? Do you upgrade what you have, or diversify your loadout?
What Makes It Fun
Lots of Spells
Homing missiles that curve toward enemies, gravity orbs that drag people in, tether beams that let you swing opponents around, meteors that crash down from above, and more.
Movement Options
Your blink ability can be swapped out for a dash that knocks people aside, an extended teleport, or a projectile that switches your position with whoever it hits.
Chaotic Upgrades
Roguelike cards stack in unexpected ways. Pair piercing shots with multishot for a wall of fireballs. Combine lifesteal with fast cooldowns to become nearly unkillable — if you can land your shots.
Round Modifiers
Vote before each round. Low gravity makes knockback absurd. Speed Demon doubles everyone's pace. Vampire rounds let you heal by dealing damage. Big Head mode makes everyone easier to hit.
The Arena Itself
The safe zone shrinks over time, pushing everyone closer together. Standing in the lava drains your health. Getting knocked into it when you're low on HP is usually a death sentence.
Customization
Pick a hat (wizard hat, crown, cat ears, pirate hat...), choose your eyes and mouth, add a trail effect, set an aura. It's all cosmetic — just for fun.
Some Tips
In Roguelike, don't sleep on the cursed cards. Paper Wizard halves your HP but doubles your damage — if you pair it with lifesteal, you can make it work. Berserker is quietly one of the strongest cards because it lets you machine-gun fireballs when you're about to die.
In Arena, cheap spells with one tier upgrade tend to outperform expensive unupgraded ones. Ricochet gets scarier the more it bounces. Tether is devastating if you blink away right after connecting — the pull gets stronger with distance.
In both modes: stay away from the edge. The knockback scaling means a fireball that barely nudges you at full health will launch you across the arena when you're low. That's usually how games end.
